Numerous molecular structure descriptors, which may be used in theoretical chemistry, are the bond incident degree (BID) indices. This study is devoted to establish a general expression for calculating the BID indices of pentagonal chains and to find the extremal (maximal and minimal) values for a variety of BID indices over the certain collection of pentagonal chains with a fixed number of pentagons.
