Q.
Among $ HF,C{{H}_{4}},C{{H}_{3}}OH $ and $ {{N}_{2}}{{O}_{4}} $ , inter molecular hydrogen bond is expected :
BVP MedicalBVP Medical 2005
Solution:
$ HF $ and $ C{{H}_{3}}OH $ shows intermolecular hydrogen bonding. Hydrogen bonding is present between a highly electronegative element and hydrogen. Hence, $ C{{H}_{4}} $ and $ {{N}_{2}}{{O}_{4}} $ cant show hydrogen bonding.
