# Write the molecular formula of two consecutive members of homologous series of aldehydes. State which part of these compounds determines their (i) physical and (ii) chemical properties. - Science

Write the molecular formula of two consecutive members of homologous series of aldehydes. State which part of these compounds determines their (i) physical and (ii) chemical properties.

#### Solution

Molecular formula of two consecutive members of homologous series of aldehydes:-

CH3-CHO and CH3-CH2-CHO

In CH3-CHO compound, -CHO part and in CH3-CH2-CHO, -CH2-CHO part will determine their physical and chemical properties.

Concept: Homologous Series of Carbon Compound
