hey i saw that there is diff in rings OH which means it make it chiral right?

Yup.

 

[♣♠ Magnanimous ♣♠]

Yup.

hey but what i think that due to presence of OH it does not make it chiral and i think the place of OH in rings is not important i think so

The rings are different and yeah place of OH does not matter I think so too.

i think it should be D but i am still unsure about the 4 diagram .. ZaqZainab help here Kamihus you too please

I was right wo-hoo

The C attached to CH3 is chiral as one H is attached to it and other 2 sides are different as from one O is nearer.

hmm.. i was thinking the reason what you said but as always some unsure

Why 1 isnt Chiral?

it's pretty embarrassing that even i have to ask a doubt. will someone answer me?

i was kidding
dekho sad kitne khush howe hein kitkat <3 :P

The C attached to CH3 is same from both sides as it is closed.

LOL mujhy waisy hee yaqeen nahi aaraha tha

There is something i wanted to tell you which might be coming tomorrow.
When bromine(aq) react with ethene we get a bromoethanol
i mean if bromine is aqueous then OH and Br will be added to the double bond. By posting doubt i wanted to see how many of you already knew this. this question was in a paper from which many 2013 papers were repeated. it an old paper not found on Xtremepapers

Thnx for sharing
can u share the link for this paper
to wat time r u available today??

is this a chiral -->
bro chiral centre means four DIFFERENT groups attached to it! but here i can see that CH2 is repeating so it is not a chiral
