2)TV cabinets. (polystyrene polymer)
3) composites for golf clubs. (carbon fibre reinforced polymer CFRP)
4) fibers for clothing and carpet. (acrylic and nylon)
5) foams for coffee cups (polystyrene)
Explanation:
a. LiCl is an ionic molecule whereas water is a polar molecule with net dipole moment in it. There LiCl in water would have an ion-dipole force of interaction.
b. Both NF3 and CH3CN have dipole moment in them, since both are polar molecule. Hence, there would be dipole-dipole interaction.
c. Here both CCl4 and benzene are non polar molecules therefore, they have London dispersion force of interaction.
d. In methylamine and water both have hydrogen bonding in them. The nitrogen of CH3NH2 forms hydrogen bond with water.
Hi the answer is C. I believe.
