Arrange the following : (i) C_(6)H_(5)overset(*)(C)HCH_(3), C_(6)Hove

1.	Arrange the following : (i) C_(6)H_(5)overset()(C)HCH_(3), C_(6)Hoverset()(C)HCH = CH_(2), C_(6)H_(5)CH_(2)overset()(C)H_(2), C_(6)H_(5)overset()(C)(CH_(3))_(2) in order of increasing stability. (ii) CH_(3)CH_(2)^(+), C_(6)H_(5)CH_(2)^(+), (CH_(3))_(3)C^(+), CH_(2) =CHCH_(2)^(+) in order of decreasing stability. (iii) HC -= C^(-), CH_(2) = CH^(-), CH_(3)CH_(2)^(-), CH_(3)^(-), (CH_(3))_(2)CH^(-), C_(6)H_(5)CH_(2)^(-)in order of increasing stability.
Answer» Solution :`(i) C_(6)H_(5)CH_(2)overset()(C)H_(2) lt C_(6)H_(5)overset()(C)HCH_(3) lt C_(6)H_(5)overset()(C)(CH_(3))_(2) lt C_(6)H_(5)overset()(C)H - CH = CH_(2)`. (ii) `(CH_(3))_(3)C^(+) gt C_(6)H_(5)CH_(2)^(+) gt CH_(2) = CHCH_(2)^(+) gt CH_(3)CH_(2)^(+)`. (iii) `(CH_(3))_(2)CH^(-) lt CH_(3)CH_(2)^(-) lt CH_(3)^(-) lt CH_(2) = CH^(-) lt C_(6)H_(5)CH_(2)^(-) lt HC -= C^(-)`.
