EXERCISE 4B

Organic compounds having the same molecular formula, but different structural formulae are called-

The members of same class of organic compounds when arranged in the order of ascending molecular mass, such that they differ from each other by $-{\mathrm{CH}}_2$ group are called :

Amongst $\left(\mathrm{a}\right){\mathrm{C}}_4{\mathrm{H}}_{10}, \left(\mathrm{b}\right){\mathrm{C}}_3{\mathrm{H}}_8, \left(\mathrm{c}\right){\mathrm{C}}_5{\mathrm{H}}_{12}$ and $\left(\mathrm{d}\right){\mathrm{C}}_5{\mathrm{H}}_{10}$ the homologues are:

A homologous series of unsaturated hydrocarbons, characterised by the presence of triple covalent bond in straight chain carbon compound is called :

Carbon forms four covalent bonds by sharing its four valence electrons with four univalent atoms, e.g., hydrogen. After the formation of four bonds, carbon attains the electronic configuration of -

Write names of alkenes having two and three carbon atoms respectively.

What is a functional group? Give examples of four different functional groups.

Give the general name of the class of compounds having the general formula C_nH_2n-2.
