Question

please suggest me answer ​

Answer 1

Answer:

Bond length Is inversely proportional to bond strength

Option B

Explanation:

Answer 2

Correct option is (b)

C--H = 107

C=C = 134

C--O = 141

C--C = 154

Values should bot be learnt.

I gave it to you just for comparision.

Now let us understand the concept.

(About option a and d )

=>There should be no doubt that Bond length of a double bond is shorter than that of a single bone.

(B/w same atoms ). Therefore option a and D can be eliminated by this concept.

2 Option

=>the size of hydrogen is very less as compared to that of carbon and also the electronegativity of carbon is more than that of hydrogen therefore it will attract hydrogen to a greater extent even than that of a double bond.

Option c

=> electronegativity increases as going from left to right in a period but as Oxygen and Carbon lies just opposite to each other yes there is a difference in electronegativity of the two but that is not more than that of carbon and hydrogen.

From this concept efficiency can also be eliminated

From this what i want to explain you that is -----"more is the difference of elecro-vity ..shortwr will be the bond
