    In HCN, the valence electron configuration of H = 1s¹

    C = 2s²2p²

    N = 2s²2p³

    Thus, in HCN, C is the central atom which is bonded to H through a single bond and to N through a triple bond. In addition, there is a lone pair of electron on N atom. The 3 atoms lie in a straight line with a bond angle of 180⁰

    Hence, the 3D shape of HCN is linear

    Ans. B) Linear
