(A) (i) Draw the structure of the following compounds :
(a) Butanoic acid (b) Chloropentane
(ii) How are structure (i) and structure (ii) given below related to one another ? Give reason to justify your answer.
Structure (i): CH3 and CH3 groups each attached to a CH, the two CH carbons joined together (CH3\CH–CH/CH3 with CH3 also below each CH)
Structure (ii): a central C attached to three CH3 groups and one CH2CH3 group (CH3-C(CH3)2-CH2CH3 pattern, drawn as CH3 above, CH3 and CH3 to the left, CH2CH3 to the right of the central C)
Draw one more possible structure for above case.
(iii) Differentiate between saturated and unsaturated carbon compounds on the basis of their general formula.
Solution
(A) (i) (a) CH3-CH2-CH2-COOH
(b) CH3-CH2-CH2-CH2-CH2-Cl
(ii) Isomers
Because they have same molecular formula but different structures
CH3–CH2–CH2–CH2–CH2–CH3
CH3–CH2–CH2–CH(CH3)–CH3
CH3–CH2–CH(CH3)–CH2–CH3
[any one]
(iii) Saturated Compounds: CnH2n+2; The number of H atoms is more than twice of 'C' atoms
Unsaturated Compounds: CnH2n and CnH2n-2; The number of H atoms is either equal to or less than twice of C atom
(Any one)
