NEET Chemistry NEET PYQ-Polymers

  • question_answer
    The straight chain polymer is formed by [AIPMT (S) 2009]

    A) hydrolysis of \[4l-2\] followed by condensation polymerization

    B) hydrolysis of \[2{{n}^{2}}\]followed by condensation polymerization

    C) hydrolysis of \[\Delta H\] by addition polymerization

    D) hydrolysis of \[\Delta S\]followed by condensation polymerization

    Correct Answer: B

    Solution :

    [b]
    (trichloro derivatives) on hydrolysis followed by nndensadon polymerisation yields branched chain silicones.
    Straight chain silanes are silicone oils. These are more stable at high temperature than mineral oils and have less tendency to thicken at low temperature.
