NEET Chemistry NEET PYQ-Nitrogen Family

  • question_answer
    Nitrogen forms \[{{N}_{2}},\] but phosphorus when form \[{{P}_{2}}\] readily converted into \[{{P}_{4}},\] reason is: [AIPMT 2001]

    A) triple bond present between phosphorus atom

    B) \[{{P}_{\pi }}-{{P}_{\pi }}\] bonding is weak

    C) \[{{P}_{\pi }}-{{P}_{\pi }}\] bonding is strong    

    D) multiple bond form easily

    Correct Answer: B

    Solution :

    [b] Nitrogen form \[{{N}_{2}}(i.e.,\text{ }N\equiv N)\] but phosphorus form \[{{P}_{2}},\] it is at a time convert in \[{{P}_{4}},\] because in \[{{P}_{2}},\] \[{{P}_{\pi }}-{{P}_{\pi }}\] bonding is present which is a weaker bonding due to larger size.
