Single Covalent Bond

Covalent Bonding

How many sigma (sigma) and pi (pi) bonds are present in each of the following molecules? (i) CH_(2) = C = CH_(2) (ii) CH_(3) - CH = CH - C -= C - CH_(3) Strategy: Every single covalent bond is a sigma (sigma) bond, every double covalent bond consists of one sigma (sigma) and one pi (pi) bond, and every triple covalent bond consists of one sigma (sigma) and two pi (pi) bonds.

The table given below lists the bond dissociation energy (E_("diss")) for single covalent bonds formed between C and atoms A, B, D, E. {:("Bond",,,E_("diss")("kcal mol"^(-1))),(C-A,,," "240),(C-B,,," "382),(C-D,,," "276),(C-E,,," "486):} Which of the atoms has smallest size ?
