Question

(a) What are hydrocarbons? Explain with examples.
(b) Explain the meaning of saturated and unsaturated hydrocarbons with two examples each.
(c) Give the names and structural formulae of one saturated cyclic hydrocarbon and one unsaturated cyclic hydrocarbon.
(d) Give one example of a hydrocarbon, other than pentane, having more than three isomers.
(e) How many isomers of the following hydrocarbons are possible?
(i) C3H8
(ii) C4H10
(iii) C5H12
(iv) C6H14

Answer 1

Answer:

The molecule of water and hydrogen

is called hydrocarbon.

example :saturated -alkane

Unsaturated: alkene and alkyne

Answer 2

Explanation:

a)Hydrocarbon is one of the organic compound comprises of only Hydrogen(H) and Carbon(C) atoms.few of its example are ethane,methane,etc

b)Saturated hydrocarbons tends to include all the hydrocarbons which have carbon-carbon single bond and generally known as Alkanes eg Ethane.On the other hand hydrocarbon which have the triple or double bond between carbon atoms are known to be unsaturated hydrocarbons eg-Propene, Pentyne

c)Cyclohexane  is a good example of saturated cyclic hydrocarbon.

Benzene is a good example of unsaturated cyclic hydrocarbon.

d)Hexane is good  example of a hydrocarbon which have almost more than three isomers.

e)The number of isomers present in the following are :

(i) There is no isomers of propane  

(ii)  Butane has two isomers-n-butane and iso-butane.

(iii)  Pentane has thee isomers.  

(iv)  Hexane has five isomers.
