Question

Assertion (A): All the carbon atoms in H₂C = C = CH₂ are sp² hybridised

Reason (R): In this molecule all the carbon atoms are attached to each other by double bonds.

विकल्प

• Both A and R are correct and R is the correct explanation of A.

• Both A and R are correct but R is not the correct explanation of A.

• Both A and R are not correct.

• A is not correct but R is correct.

Answer 1

A is not correct but R is correct.

Explanation:

Since hybridization of C can be found out by counting σ bonds and π bonds present on C atom. This can be shown as-

\[\ce{\overset{3α}{\underset{1π}{CH2}} = \overset{2α}{\underset{2π}{C}} = \overset{3α}{\underset{1π}{CH2}}}\]

If C has 3σ bonds then it is sp² hybridized. If C has 2σ bonds then it is sp hybridized.
