Question

Write any two characteristics of homologous series. Write third
member of alknals.​

Answer 1

Answer:

A uniform steel wire of length 3 m and area of cross section 2 mm² is extended through 3 mm. Calculate the energy stored in the wire, if the elastic limit is not exceeded. ( = 20 x 10¹⁰ N / m²) (Ans 0.6 J)A uniform steel wire of length 3 m and area of cross section 2 mm² is extended through 3 mm.

Answer 2

Explanation:

Characteristics of a homologous series are:

(i) Each member of the series can be represented by a general formula.

(ii) All the members of the series can be prepared by the same general methods.

(iii) Physical properties changes throughout the series in a regular way.

(iv) Members of homologous series have similar chemical properties.

Thus the first four members of alkane homologous series are CH 4

(methane), CH3 −CH 3 (Ethane)

, CH 3−CH 2−CH 3 (propane)

and CH 3 −CH 2 −CH 2 −CH3 (butane).
