HeyHi guys ,Can anyone tell me Is it permissible for rough work that includes underlining statements of questions ,I do that because it helps me understand questions better,So can we do excessive rough work? I mean its not like excessive excessive just like underlining statements or a simple cut when solving an answer here and there.
is it allowed?
https://www.quora.com/Why-doesnt-Benzene-undergo-addition-reactionscan anyone explain why benzene does not undergo nucleophillic addition ????
yep it helped a lot thanks alothttps://www.quora.com/Why-doesnt-Benzene-undergo-addition-reactions
Hope this makes ur thinking crystal clear
Anytimeyep it helped a lot thanks alot
Ans is A because hydrogen bonding occurs when hydrogen is bonded to a highly electronegativexperienced atom like N,O,F etc. So only a will fulfill that condition.help plz
Hydrogen bonding can occur between molecules of methanol, HCHO, and molecules of liquid Y. What could liquid Y be? A. CH3OH B. CH3CHO, C. CH3COCH3 D. CH3CO2CH3
1 and 2 are correct. 3 is wrong.HELP PLZZZZZZ
Which physical properties are due to hydrogen bonding between water molecules?
1 Water has a higher boiling point than H2S
2 Ice floats on water
3 The H-O-H bond angle in water is approximately 104
B?7. Use of the Data Booklet is relevant for this question. In an experiment, the burning of 1.45g (0.025mol) of propanone was used to heat 100g of water. The initial temperature of the water was 20.0°C and the final temperature of the water was 78.0°C. Which experimental value for the enthalpy change of combustion for propanone can be calculated from these results? A –1304kJ mol–1 B –970kJ mol–1 C –352kJ mol–1 D –24.2kJ mol
D?X is the oxide of a Period 3 element. X reacts with water to give an acidic solution. A solution is prepared by reacting 0.100g of X with excess water. This solution was neutralised by exactly 25.0cm3 of 0.100moldm–3 sodium hydroxide solution. What could be the identity of X?
A. Al 2O3
B. MgO
C. P4O10
D. SO3
B?Q.25 anyone please reply soonn
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.
