Answer to Question #317699 in General Chemistry for Ywhxbsj

Question

Answer the following questions.

1. (a) The formula of six compounds are given below.

C3H8, CH3CH2OH, CH3-O-CH2-CH3, HCOOH, CH3COOH

(i) Name the type of intermolecular forces present in the compounds.

(ii) Arrange these compounds in the order of increasing boiling point. explain your answer.

(i) Explain the polarity of the following simple covalent molecules: H2O, CO2, and SO2.

(ii) Which is the most polar molecule amo them? Explain.

Answer 1

I) hydrogen bonding

Ii)C3H8, CH3CH2OH, CH3-O-CH2-CH3, HCOOH, CH3COOH

I)Co2 is a linear molecule and the oxygen atoms on each end are symmetrical . Whereas SO2 molecule is bent shaped and is polar because of the electronegativity difference between sulphur and oxygen . Resulting in a net dipole moment . This doesn’t occur in CO2 molecule hence its non polar

Ii) H2O is most polar
