I guess the first reaction was for an aldehyde being oxidised to a carboxylic acid. I wrote orange to green. I don't think it was a tertiary alcohol. The compound to be oxidized was (CH3)3CHO. Wouldn't the aldehyde group be oxidized to a carboxylic acid?
how can carbon form 6 bonds if its an aldehyde :S

Oh I drew the 3d formula as that is the only way to 'show' two optical isomers. :/ most of the students found organic part tricky.

-Q5 doubt!

In isomerism part, i drew a cis-trans in first one.

Didn't knew what to do in second part. So i drew structural isomer. :(

What do you guys think?
the other shoul be optical... as they asked for sterio isomers

Do you remember the exact wording in the question?

How can we draw an optical in a C=C?

Did the question said "also" stereo isomerism?
I don't remember anything. :confused:
for C=C we have to draw cis-trans.. and optical for the one having chiral center
