Than why not B

bcuz it's talkng abt the bong energy

bcuz it's talkng abt the bong energy

i didn't get!! in book it is written na in table that fluorine has strong bond and iodine has weak bond so i thought B in ans but i didn't get what you said

I'd go with B.

And, D?

What're the answers? Its actually easier for to help if the papers are linked. That way one can answer, then check if it's correct. No point giving a wrong explanation.

View attachment 43749help me out!! why not B and answer is C. Why?

I think it's because it's talking about why the first reaction itself was faster, C-N & C-I bonds are formed after the reactions have taken place.

View attachment 43749help me out!! why not B and answer is C. Why?

I think the question has nothing to do with the bond strengths of C-N. CN will attach to the carbon as a whole, like CN-. Reaction 1 is faster bcoz CN- is a stronger nucleophile than the I- ion and thus will attack the C atom more strongly.

 

[omarjaved619]

Heulp! Answer is D (means only 1 is correct). I understood the other two statements. But I just cant seem to figure out why W will neutralize more acid than X?

I'd go with B.


And, D?

[♣♠ Magnanimous ♣♠]

My answer is C but the answer is D so anyone explain please!

Look First Reaction is Slow Hence Higher Activation Energy So ans IS D..! Get it ?

elaborate please

 

[Mohammed salik]

elaborate please

* Feeling Lazy *
Look it Is Slow Meaning it has Higher Activation Meaning It will Have Longer Hump or Whtever is that thingy..! The other One has A fast Reaction Meaning Lower Activation Energy ( that Curved Part Below The First One) So D!
