Here is a sneak peek of the questions included in this test set. Test your preparation by viewing the answer and detailed explanation before starting the timed exam.

Q1
What is the **Gabriel Phthalimide Synthesis** and why can it NOT be used to prepare aromatic primary amines (Aniline)?
എന്താണ് **ഗബ്രിയേൽ ഫ്താലിമൈഡ് സിന്തസിസ്**, ആരോമാറ്റിക് പ്രൈമറി അമിനുകൾ (അനിലിൻ) തയ്യാറാക്കാൻ ഇത് NOT ഉപയോഗിക്കുന്നത് എന്തുകൊണ്ട്?
A
Gabriel synthesis produces tertiary amines onlyഗബ്രിയേൽ സിന്തസിസ് ത്രിതീയ അമിനുകൾ മാത്രമേ ഉത്പാദിപ്പിക്കുന്നുള്ളൂ
B
Phthalimide reacts with ethanolic KOH to form Potassium phthalimide, which undergoes S_N2 alkylation with a **PRIMARY ALKYL HALIDE (1°\ R-X)** followed by alkaline hydrolysis to yield a **PURE PRIMARY ALIPHATIC AMINE (R-NH_2) FREE FROM SECONDARY/TERTIARY CONTAMINATION**; Cannot prepare Aniline because **ARYL HALIDES (Ar-X) DO NOT UNDERGO S_N2 DISPLACEMENT BY PHTHALIMIDE ANION DUE TO PARTIAL DOUBLE-BOND RESONANCE CHARACTER**Phthalimide എത്തനോലിക് KOH-മായി പ്രതിപ്രവർത്തിച്ച് പൊട്ടാസ്യം phthalimide ഉണ്ടാക്കുന്നു, ഇത് S_N2 ആൽക്കൈലേഷനു വിധേയമായി **PRIMARY ALKYL HALIDE (1°\ R-X)** തുടർന്ന് ആൽക്കലൈൻ ജലവിശ്ലേഷണം നടത്തി **PURE PRIMARY__C6 ലഭിക്കും. FROM SECONDARY/TERTIARY CONTAMINATION**; അനിലിൻ തയ്യാറാക്കാൻ കഴിയില്ല കാരണം **ARYL HALIDES (Ar-X) DO NOT UNDERGO S_N2 DISPLACEMENT BY PHTHALIMIDE ANION DUE __C**C**C25____8BOND-BOND
C
Phthalimide is explosivePhthalimide സ്ഫോടനാത്മകമാണ്
D
Aniline reacts with potassium to form gasഅനിലിൻ പൊട്ടാസ്യവുമായി പ്രതിപ്രവർത്തിച്ച് വാതകം ഉണ്ടാക്കുന്നു
Correct Answer: Option B
Explanation:
Gabriel phthalimide synthesis produces pure 1 deg aliphatic amines via S_N2; aryl halides cannot undergo S_N2, precluding aniline synthesis.
ഗബ്രിയേൽ ഫത്താലിമൈഡ് സിന്തസിസ് S_N2 വഴി ശുദ്ധമായ 1 ഡിഗ്രി അലിഫാറ്റിക് അമിനുകൾ ഉത്പാദിപ്പിക്കുന്നു; ആറിൽ ഹാലൈഡുകൾക്ക് അനിലിൻ സിന്തസിസ് ഒഴിവാക്കിക്കൊണ്ട് S_N2-ന് വിധേയമാകാൻ കഴിയില്ല.
Q2
What is the **Hoffmann Bromamide Degradation Reaction** for preparing primary amines from amides?
അമൈഡുകളിൽ നിന്ന് പ്രാഥമിക അമിനുകൾ തയ്യാറാക്കുന്നതിനുള്ള **ഹോഫ്മാൻ ബ്രോമമൈഡ് ഡിഗ്രഡേഷൻ റിയാക്ഷൻ** എന്താണ്?
A
An acid amide (R-CONH_2) is treated with **BROMINE IN AQUEOUS OR ETHANOLIC SODIUM HYDROXIDE (Br_2 + 4NaOH)** to yield a **PRIMARY AMINE HAVING ONE FEWER CARBON ATOM (CARBON CHAIN SHORTENED BY ONE CARBON)**: **R-CONH_2 + Br_2 + 4NaOH → \mathbf{R-NH_2} + Na_2CO_3 + 2NaBr + 2H_2O** (Proceeds via acyl nitrene and alkyl isocyanate intermediate R-N=C=O)ഒരു ആസിഡ് അമൈഡ് (R-CONH_2) **BROMINE IN AQUEOUS OR ETHANOLIC SODIUM HYDROXIDE (Br_2 + 4NaOH)** ഉപയോഗിച്ച് **PRIMARY AMINE HAVING ONE___C4 (______________C12) CHAIN SHORTENED BY ONE CARBON)**: **R-CONH_2 + Br_2 + 4NaOH → \mathbf{R-NH_2} + Na_2CO_3 + 2NaBr + 2H_2O** (അസൈൽ നൈട്രീൻ, ആൽക്കൈൽ ഐസോസയനേറ്റ് ഇൻ്റർമീഡിയറ്റ് വഴിയുള്ള വരുമാനം R-N=C=O)
B
An amide is heated with ammoniaഅമോണിയ ഉപയോഗിച്ച് ഒരു അമൈഡ് ചൂടാക്കുന്നു
C
An amide is reduced with LiAlH_4ഒരു അമൈഡ് LiAlH_4 കൊണ്ട് കുറയുന്നു
D
An amide is chlorinated with PCl_5ഒരു അമൈഡ് PCl_5 ഉപയോഗിച്ച് ക്ലോറിനേറ്റ് ചെയ്യുന്നു
Correct Answer: Option A
Explanation:
Hoffmann bromamide reaction: RCONH_2 + Br_2 + 4NaOH → R-NH_2 + Na_2CO_3 + 2NaBr + 2H_2O, shortening carbon chain by 1 carbon.
ഹോഫ്മാൻ ബ്രോമമൈഡ് പ്രതികരണം: RCONH_2 + Br_2 + 4NaOH → R-NH_2 + Na_2CO_3 + 2NaBr + 2H_2O, കാർബൺ ശൃംഖല 1 കാർബൺ കൊണ്ട് ചുരുക്കുന്നു.

How Chapter-Wise Online CBT Tests Build Winning Habits for Future Competitive Exams

Early practice in high school builds the mental muscle, speed, and analytical discipline required to ace NTSE, Olympiads, JNVST, CUET, and Foundation JEE/NEET.

Competitive Edge

Real-Time Clock Awareness & Pacing

समय प्रबंधन एवं गति नियंत्रण

In school examinations, students write answers without active pacing. In national entrance tests, students have barely 45-60 seconds per MCQ. Practicing with a 20-minute timer instills instinctive time-budgeting and prevents last-minute exam panic.

Mastery of the Elimination Technique

विकल्प निष्कासन विधि में दक्षता

Top rankers in competitive exams rarely compute every problem blindly. They spot subtle traps, evaluate extreme values, and eliminate 2 out of 4 distractors within seconds. Our 4-option sets teach critical distractor analysis.

CBT Screen Stamina & Digital Comfort

कंप्यूटर आधारित परीक्षा का सहज अभ्यास

Almost all major national exams (CUET, JEE, NEET, SSC, Banking) are 100% computer-based. Students who only study on paper experience eye strain and navigation mistakes on exam day. Early CBT practice creates effortless digital fluency.

Immunity to Negative Marking

सटीकता और नकारात्मक अंकन से सुरक्षा

Careless errors—such as misreading "NOT" or "EXCEPT"—ruin thousands of competitive aspirations each year. Regular objective testing builds the habit of double-checking question keywords before locking answers.

Instant Diagnostic Feedback Loop

तत्काल त्रुटि निवारण एवं आत्म-मूल्यांकन

Traditional paper tests take weeks to grade, by which time the student has forgotten their thought process. TargetExams provides instant scorecards and step-by-step solutions while the conceptual puzzle is still fresh.
