question 29
idono why i cant solve isomer question everytime !!!! TT
An easy, albeit time consuming way to figure these questions out is to simply draw the isomers. You know there's a double bond, so it must show geometric isomerism - cis and trans, that makes 2. But they aren't asking for just geometric isomers, they're asking for all the isomers. Another one would be but-1-ene. So that makes 3. I know this isn't the best way to work it out, but it's better than nothing.
The question says 'structural or otherwise' :S I don't know, I could be wrong.
Could you or someone else help me with the questions I posted earlier? Just on the previous page.
but there is a differenc betweeen structural and stereo isomers isnt it :/?
well i think the cis and tra wont be included in this one :/
who i n helll will think to do this correct only 1 mark omg jesus christ the merciful
MJ 2008 Q27!!!some1 plz explain
so whenester bond is broken only one hydroxyl group and one cooh group is formed right then na substitutes them to get alkoxide right
5.175 then watGas X =N02
Gas Y =O2
2Mg(NO3)2 = 2MgO + 4N02 +O2
mass of gas X (NO2) produced =4*(mr of NO2)=4(46)=184
mass of gas Y (O2) produced =mr of O2=32
X/Y=184/32=5.75=1/0.174=5.75
answer = A
mass of nitrogen in 14 g = 15/100 * 14 = 2.1help urGENT PLZZZZZZZZzView attachment 45080
