Question

In the following molecule:
The hybridisations of carbon a, b and c respectively are:

• A. $s{p}^3,s{p}^2,s{p}^2$
• B. $s{p}^3,s{p}^2,sp$
• C. $s{p}^3,sp,sp$
• D. $s{p}^3,sp,s{p}^2$

Answer 1

The correct option is A $s{p}^3,s{p}^2,s{p}^2$

Answer: (a)
$a\to s{p}^3$
It is attached to 3 hydrogens and 1 carbon atom

$b\to s{p}^2$
It is attached to carbon by double bond and to oxygen and hydrogen via single bond.

$c\to s{p}^2$
It is attached to carbon by double bond and to another carbon and oxygen via single bond.
