• # question_answer Identify the non-polar molecule in the set of compounds given : $HCl,\,HF,\,{{H}_{2}},\,HBr$ [UPSEAT 2004] A)                 ${{H}_{2}}$       B)                 $HCl$ C)                 $HF,\,HBr$       D)                 $HBr$

Polarity create due to the difference in electronegativity of both atom in a molecule except ${{H}_{2}}$ all other molecule have the different atom so they will have the polarity while ${{H}_{2}}$ will be non-polar.
