Question

In which molecule the interaction of hydrogen bond is present. [A] * C * H_{4}; [B] * H * F [C]SiH₁ [D]MgH₂​

Answer 1

A hydrogen bond (or H-bond) is a primarily electrostatic force of attraction between a hydrogen (H) atom which is covalently bound to a more electronegative atom or group, and another electronegative atom bearing a lone pair of electrons—the hydrogen bond acceptor (Ac). Such an interacting system is generally denoted Dn–H···Ac, where the solid line denotes a polar covalent bond, and the dotted or dashed line indicates the hydrogen bond.[4] The most frequent donor and acceptor atoms are the second-row elements nitrogen (N), oxygen (O), and fluorine (F)
