    I thought in graphite not only covalent compounds are involved but Van der Waals forces between the layers are also there. So D is therefore not possible.

    Biology; Chemistry; Physics: Post your doubts here!

    I don't remember. Plus I don't think that this method would be acceptable because in the first trial you are unsure as to what amount of acid is needed to JUST titrate the base and that's why you use the indicator. Even with indicator you, unknowingly, add slightly more amount of acid to the...

    Oh, in fats, the glycerol (alcohol monomer) has three OH- groups. And in alcohols in terylene, 2 OH- groups.

    Both contain Dicarboxylic acids and Di-alcohols as monomers. I guess no change in the structure (both have ester linkage). Just that fats are natural polymers, and the other is synthetic.

    "describe methods of purification by the use of a suitable solvent" Does this mean that if two substances are mixed together, they can be separated by using a solvent in which only one of the 2 dissolves, and then filtering the insoluble substance to separate?

    1 & 2) Terylene itself is a polyester. And as the name suggests, the linkages are ester-type (COO and O). Monomers: Dicarboxylic acids and Diol. 3 & 4) Nylon and Protein both have amide linkages. Monomers: Dicarboxylic acids and Diamines 5) Fats are made from fatty acids and glycerol. (same...

    In each, Only H atoms are removed from Carboxylic acids, and OH from Alcohols. This forms water, while the remaining part is the ester. You always draw* the remaining acid part first and then the alcohol part. Try doing yourself and post your answers here, I'll check them :D *Like A Teacher(Boss)*
