Most of the People were confused between B and D

I did B :/
yeh i went with 10.8 ... I mean if oxygen is being released as a gas... it's a diatomic molecule by defualt, you have to use 32.. oxygen atoms dont chill alone.. as 16 and 16.. so it shouldnt be 21.6

how does iodine have different type of bonding? I did the magnesium compound ..cause magneseium has metallic bonding and the compound itself was ionic.
it was asked I2 solid that means I2 molecule had covalent bonds between 2 I atoms like I-I and its has van der waals forces between molecules

I Believe it was A Bond energy also increases
thats not true ..bond length increases down the group ,so bond energy decreases....I guess the option was -Bond energy -increase
Bond polarity-decrease
Bond length -increase
...the answer should be C ,2 and 3 correct.

Answer to the equilibrium question was D (2P <---> Q+2R)
Answer to largest overall dipole was B
Answer to ester hydrolysis was C 42.3% and 57.7%
Answer to coiine question was IMO B (unclear)


btw what was the answer to the 3 possible products When HBr reacts with the two cis-trans structures?
answer to coiine was D as nitrogen was bonded with 1st and 5th carbon oh the chain
and answer to 3 possible products was B
and with alkaline hydrolysis one alcohol is produced and other is the salt of metal present in alkali used which reacts with the carboxylic acid to form that salt...:)
