no, it was hydration or u cud also write electrophilic addition!!

 

[Nisrit Pandey]

what if i wrote CHO only??how manny marks will be deducted?

you will get a 2! because you must have written the ratio and given it in terms 1:1.33:1.16

Wonder how many marks would have been lost if i drew the cis trans isomers in the usual displayed formula rather than skeletal formula? :/

 

[Nisrit Pandey]

Dude do u remember how many marks it was for the enthalpy question they asked how rate of formation depends on temp and pressure....

it was 6 marks 2 each!

 

[Nisrit Pandey]

Wonder how many marks would have been lost if i drew the cis trans isomers in the usual displayed formula rather than skeletal formula? :/

you will get a zero

best of luck

 

[Nisrit Pandey]

Sulfur also burns in blue flame for gods sake.....
