Consider the following compounds A. Chloroethene B. Benzene C. 1,3-butadiene D. 1,3,5-hexatriene All the carbon atoms are sp^(2) hybridised in

Note: In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices. Assertion : In allene (C_3 H_4) all carbon atoms are sp^2 hybridised. Reason : All the three carbon atoms are joined by double bond.

Consider the given statement about the molecule 1. Three carbon atoms are sp^(3) - hybridised 2. Three carbon atoms are sp^(2)- hybridised 3. Two carbon atoms are sp - hybridised

Consider the given statement about the molecule 1. Three carbon atoms are sp^(3) - hybridised 2. Three carbon atoms are sp^(2)- hybridised 3. Two carbon atoms are sp - hybridised

Assertion: Alkanes containing more than three carbon atoms exhibit chain isomerism. Reason: In an alkane, all carbon atoms are sp^(3) hybridised.

All carbon atoms sp^(2) hybridised in

In CH_2 = C = CH_2 , all the carbon atoms are sp^2 hybridised.

Which one of the following reagents is used to get sp^(3) - hybridised carbon atom from sp^(2) -hybridised carbon atom?
