  • 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.

 In the following questions a statement of Assertion (A) followed by a statement of Reason (R) is given. Choose the correct option out of the choices given below each question.

Assertion (A): All the carbon atoms in H_{2}C=C=CH_{2} are sp^{2} hybridised

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

(i) Both A and R are correct, and R is the correct explanation of A.

(ii) Both A and R are correct, but R is not the correct explanation of A.

(iii) Both A and R are not correct.

(iv) A is not correct but R is correct.

Answers (1)

The answer is the option (iv) A is not correct, but R is correct.

Explanation: Hybridisation of C can be found out by counting the number of \sigma bonds and \pi bonds present on the C atom. If C has 3\sigma bonds, it is sp^2 hybridised. If C has 2\sigma bonds, it is sp hybridised.
