We are currently struggling to cover the operational costs of Xtremepapers, as a result we might have to shut this website down. Please donate if we have helped you and help make a difference in other students' lives!

It is D because tertiary alkyl halides undergo reactions with SN-1 mechanism. This mechanism is independent of the concentration of reactantsHelp please!!!!!
When an isomer Y of molecular formula C4H9Br undergoes hydrolysis in aq. alkali to form an alcohol C4H9OH, the rate of reaction is found to be unaffected by changes in concentration of the OH- ions present. Which is the most likely molecular structure of Y?
A CH3CH2CH2CH2Br
B CH3CH2CHBrCH3
C (CH3)2CHCH2Br
D (CH3)3CBr
The Ans is D......
Total 3 valance pair.. so 120 degress or slightly lesser than 120View attachment 54751
N forms 2 bond pairs and 1 lone pairs here right??
Then why 120degrees? wouldn't it be A?
Q9 C=C=O ; O have 2 LP and C have 1 LP
Propanone doesnt have H-bonding... It can not be mixed properly with propanalView attachment 54756
Why is 3 wrong? If something can form H-bonds then it will mix right?
How 3 valence pairs? Don't you only count the sigma bonds and not the pi bonds? and what about the 1 lone pair?Total 3 valance pair.. so 120 degress or slightly lesser than 120
Q9 C=C=O ; O have 2 LP and C have 1 LP
The question says that the statements are all truePropanone doesnt have H-bonding... It can not be mixed properly with propanal
2) 68-31 = 37
NO :/The question says that the statements are all true
but just asks which ones are associated with H-bonding
So doesn't the mixing depend on H-bonding?
2 BP and 1 LP = 3 valance par of electorns..How 3 valence pairs? Don't you only count the sigma bonds and not the pi bonds? and what about the 1 lone pair?
Oh haha thanks! idk my head was screwed up xD2 BP and 1 LP = 3 valance par of electorns..
I think its enthalpy change per mole H20 formed,as same moles formed and enthalpy of neutralisation is mostly 56-57 its C.
Why is it the same??
Transition elements.Cu and Mg can have +2 but they arent in same group
How is 2 correct? Why are they both metals?
And why is 3 wrong? They both form +2 so can they not be in the same group?
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
