Question

Which is not correct order of acidic strength-
O HI > HBr > HCI > HF
O HF > H2O > NHz > CH4
O CH3 -SH > CH3-OH
0 CH3-CH2-CH2=CH->HC=CH​

Answer 1

Answer:

CH3CH2CH2=CH > CH=CH is the wrong answer

Explanation:

this is because butene has more +I groups on it

and acidity is inversely proportional to +inductive effect

so butene is less acidic as compared to ethene

and this contradicts with given

4) option is wrong
