Ok i think i got it ... Thank u
Thnx............also is the cis - trans isomerism the same as EZ isomerism?There is EZ isomerism at the C=C double bonds.
3-methylbut-3-en-2-olCan anyone please name the structure: CH3CH(OH)C(CH3)=CH2?
Thnx...........
Thnx.............3-methylbut-3-en-2-ol
Yea,the substituent gets named first, next the double bond, then hydroxyl group ...Thnx.............
So we always start the numbering from the other functional group rather than the double bond? Ryt?

Thanku sooo much!Yea,the substituent gets named first, next the double bond, then hydroxyl group ...
But we number the carbons so that hydroxyl group gets the lowest number possible
Oooohkaaaayyy! I get it now.............thnx for replying and taking out ur time though.........Cis-trans and EZ are both geometrical isomers but are not the same.
Cis-trans is more specific, it requires at least 2 out of the 4 groups (at the C=C) to be identical to each other. ClCH=CHCl or ClCH=CHBr
EZ is more general, it can consist of 4 different groups. ClCH3C=CHBr
No problemThanku sooo much!
Lol ... How about organic chemistry? You'll never go wrong with that one.Any guess for the paper? Any particular topic which can come?
Organic stuff is always easyLol ... How about organic chemistry? You'll never go wrong with that one.
I wouldn't say always ... Especially finding the no. of isomers and all is just plain annoying ... But otherwise its good ... Tricky, but good.Organic stuff is always easy
True that.I wouldn't say always ... Especially finding the no. of isomers and all is just plain annoying ... But otherwise its good ... Tricky, but good.
No one knows this?? Metanoia awesomaholic101When I solve recent years past papers that is from 2007 to 2015(summer) summer and witner both I use to score always above 50. Now when I look into old years like this paper I ended up at the score of just 46. I have so many doubts in this paper. If anyone can help me out solving, Q1(c)(d), Q2(c)(d), Q5(c), Q7(b)(c) in Q7(b) arent answer in ms for uses of esters? Please do it as soon as possible. Also, When I was solving papers I found that mostly moles thingy are in summer papers, in winter papers its mostly inorganic part and theory. Am I correct? Should I expect 2015 november paper to be easier with moles thingy??
Thank you,

From where did u got a phrase like Avg. isotopic mass?Anyone please give me "Average isotopic mass" definition & tollen's reagent result... is it "silvery mirror formed" or "silvery mirror ppt." ?
