    A) Nitric Oxide                   

    B) Nitrogen Pentoxide

    C) Nitrogen Peroxide           

    D) Nitrous Oxide

    Correct Answer: D

    Solution :

    Nitrous Oxide \[\mathbf{(}{{\mathbf{N}}_{\mathbf{2}}}\mathbf{O)}\] is known as laughing gas. Nitrous Oxide is fat soluble and moves into the cells when inhaled. Nitric Oxide (NO) when inhaled relaxes muscles and widen blood vessels. It is used to treat respiratory failures. Nitrogen Pent oxide \[({{N}_{2}}{{O}_{5}})\] is used as nitrating agent in chloroform solution. Nitrogen pent oxide is a highly poisonous gas and even cause inflammation of lungs if inhaled.
