Question

Read the following statements and choose the correct option
(i) Nitrogen atom in amines is $sp^{3}$-hybridised
(ii) The geometry of amines is pyramidal
(iii) The angle $C-N-C$ or $C-N-H$ is slightly more than $109.5^{\circ}$

• A. $(i), (ii)$ and $(iii)$
• B. $(i)$ and $(ii)$
• C. $(i)$ and $(iii)$
• D. $(ii)$ and $(iii)$

Answer 1

Answer: (B)

The fourth orbital of nitrogen in all amines contains an unshared pair of electrons. Due to the presence of unshared pair of electrons, the angle $C-N-E$, (where E is C or H) is less than $109.5^{\circ}$
