NEET Chemistry Question (2026) — Solution
Options
- A. A-III, B-IV, C-II, D-I
- B. A-IV, B-I, C-III, D-II
- C. A-I, B-II, C-IV, D-III
- D. A-II, B-III, C-I, D-IV
Answer
B. A-IV, B-I, C-III, D-II
Step-by-step solution
For C _2 H _4 (Ethene), the structure is H _2 C = CH _2. It contains 4 C - H single bonds and 1 C = C double bond. A single bond is a bond, and a double bond consists of 1 and 1 bond. Total bonds: 5\ bonds and 1\ bond. Thus, A matches IV. For C _2 H _2 (Ethyne), the structure is HC CH . It contains 2 C - H single bonds and 1 C C triple bond. A triple bond consists of 1 and 2 bonds. Total bonds: 3\ bonds and 2\ bonds. Thus, B matches I. For CH _4 (Methane), the central carbon atom is bonded to 4 hydrogen atoms via single bonds. Total bonds: 4\ bonds. Thus, C matches III. For NH _3 (Ammonia), the central nitrogen atom is bonded to 3 hydrogen atoms via single bonds and has 1 lone pair of electrons. Total bonds: 3\ bonds and one lone pair. Thus, D matches II. The correct matching is A-IV, B-I, C-III, D-II. Answer: A-IV, B-I, C-III, D-II
