# General doubt in isomerism

My doubt is is the compound above chiral or not?

Please can anyone tell in conformation?

• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

Hey @neelesh vij This compound is chiral because its mirror image is non-superimposable.

Chiral as it has only one chiral centre.

The question is - Is that a chiral Centre!

- 3 years, 6 months ago

the points to favor is that both the two groups are same but they are cis and trans so the compound can be chiral. but i am not sure that's why i asked this.

- 3 years, 6 months ago

It is chiral carbon Because the left and right sides when are opposite (cis and trans ) the make the poparised light to rotate

- 3 years, 6 months ago

but the cis and trans carbons will rotate the light equally in opposite directions (as all the groups are same) so there will be no effect due to them. my main point is that whether the middle carbon will be chiral or not.

- 3 years, 6 months ago

How are you saying the cis and trans groups will rotate light in equal and opposite directions? I agree with @Gauri shankar Mishra, the compound is chiral.

- 3 years, 6 months ago

Umm. i am not sure about the statement. I thought it similar to R and S configuration. so does that mean geometrical isomers do not rotate light?

See buddy that lack of symmetry makes a compound chiral .and also tell me the question of himanshu and ms in which u have problem

- 3 years, 6 months ago

Try out ms chauhan ch: isomerism qno: 65,113,161

himanshu pandey qno: (level 2) 22

I too have doubt in himanshu Rest are done and can be explained by me( ms questions)

- 3 years, 6 months ago

I Think that This Compound Is Chiral . The central chiral atom is called pseudo chiral as the groups attached to the carbon can be different due to stereoisomerism.

- 3 years, 5 months ago

Me too.......same explanation...I am with you

- 3 years, 5 months ago

But I dont see any chiral carbon in the structure.. Do you? ANd if thats true than the compound should be achiral...

- 3 years, 5 months ago

The central carbon, the one connected to the two double bonds has 4 different groups.

- 3 years, 5 months ago

No only 3 are different- methhyl,chlorine and other two are same- I guess..

- 3 years, 5 months ago

One is the trans compound, the other is the cis one.

- 3 years, 5 months ago

Oh Now I see... Thanks.. :)

- 3 years, 5 months ago

I guess it is not but I am not sure

- 3 years, 6 months ago

In my opinion it's chiral, if one side you take E isomer and the other side the Z isomer the it would be an enantiomer and hence optically active

- 3 years, 6 months ago

This is chiral. There is a central carbon bonding with 4 different compounds.
