Which of the following statement(s) is/are correct ? (i) A carbon atom having an $s p$ hybrid orbital is less electronegative than carbon atoms possessing $s p^2$ or $s p^3$ hybridised orbitals. (ii) $\pi$-bonds provide the most reactive centres in the molecules containing multiple bonds (iii) The number of $\sigma$ and $\pi$ bonds in compound ${CH}_2={C}={CHCH}_3$ are 7 and 2 respectively.

Which of the following statement(s) is/are correct ?

(i) A carbon atom having an

s p

hybrid orbital is less electronegative than carbon atoms possessing

s p^2

s p^3

hybridised orbitals.

(ii)

\pi

-bonds provide the most reactive centres in the molecules containing multiple bonds

(iii) The number of

\sigma

and

\pi

bonds in compound

{CH}_2={C}={CHCH}_3

are 7 and 2 respectively.

View answer and explanation

Correct option: C

(ii) only

Option C ((ii) only) is correct because only statement (ii) is correct. Pi-bonds are indeed reactive centers, while (i) is incorrect as sp hybridized carbon is more electronegative, and (iii) has incorrect bond counts.
