Answer 1

@Vincent-Lyon.Fr @Kainui @emcrazy14

Answer 2

If it's not specified, either draw both or draw whichever one you like. Generally speaking though, the trans configuration is most stable.

Now there are other reasons it might not be specified, for instance, maybe it's an elimination reaction which has a specific product. Another possibility is that you have a racemic mixture, but I'm not sure what context you're asking this question so I just wanted to make sure you knew that my first answer isn't necessarily 100% correct.

Answer 3

ow okayy got it :D thank you!!! @Kainui

Answer 4

actually this is the question and my compound E is this CH3CH=CHCOOH

Answer 5

Looks like they say they want cis there?

Answer 6

yeah but its in marking scheme that they say CIS
they say nothing in question

Answer 7

@Somy : The structure given in marking scheme is trans-form. That's why they have written 'accept cis form'.

Answer 8

If it's not mentioned which form you should draw, you can draw any of the two. You'll get the marks.

Answer 9

@emcrazy14 mm ok thnx!! cuz i thought what if i draw in different way and then they won't accept it as an answer so i'll lose mark
