Weekly Quiz Competition
  • Question 1
    1 / -0

    Which of the following is a thermosetting polymer?

    Solution

    Phenolic resins falls under the clan of thermosetting polymers and rest are thermoplastic polymers which can be softened repeatedly on the application of heat.

  • Question 2
    1 / -0

    Which of the following reactants react to give amidation reaction?

    Solution

    The reaction of amine with acid is an amidation reaction which is given by-

    ─NH2 + ─COOH ↔ ─NH─CO─ + H2O.

  • Question 3
    1 / -0

    Which of the following category does cellulose nitrate fall into?

    Solution

    Cellulose nitrate is a chemically modified form of cellulose. That’s why it falls under the category of semi-synthetic polymers.

  • Question 4
    1 / -0

    Which among the following chemical bond were described by Kossel and Lewis?

    Solution

    Both Ionic and Covalent bond arise from the tendency of atoms to attain stable configuration of electrons.

  • Question 5
    1 / -0

    Which of the following monomers are unsuitable for condensation polymerization?

    Solution

    Propanoic acid and ethanol, both are monofunctional monomers which are not suitable for a polycondensation reaction to take place.

  • Question 6
    1 / -0

    How many molecules of hydrochloric acid are released when n monomers of di-acid chloride and n monomers of di-alcohol are reacted to form a polymer?

    Solution

    Here, the reaction between the monomers completes in (2n-1) number of steps. So, the molecules released will also be 2n-1.

  • Question 7
    1 / -0

    30 (in)(cm2)/(yr)(s)(lbm)(ft2) to all SI units.

    Solution

    1 lbm = 454 g, 1 ft = 12×2054 centimetres and 1yr = 365×24×60×60 sec.

  • Question 8
    1 / -0

    1.5 nm. is equal to

    Solution

    1 in. = 2.54 cm, 1 Angstrom = 10*-10 meter, 1 meter = 0.1 dm.

  • Question 9
    1 / -0

    The electronegativity difference between the covalently bonded atoms is

    Solution

    The electronegativity difference between covalent bond atoms is 0-0.3, whereas for polar covalent bonded atoms it is between 0.3-1.7 and for ionic it is over 1.7.

  • Question 10
    1 / -0

    What is the hybridization of Carbon atom in CF4?

    Solution

    CF4 has a tetrahedral structure and carbon in it has a hybridization of sp3.
