acha acha..koi gal nahihahha...galti sai posted! :/
just memorize it i think it has a difficult way to find the ratio and we r not doing a math exam to be asked how to find their ratios..that would be a stupid question from the examiner
a key point for mass spectrometryokay means koi logic nahi hai, just have to learn it Right
See.Can u like tell me the second step? as in when it says, sin45=real p/ 2(1+2^1/2)=1/2^1/2 ?? :S
Are we Google?do we need to know it?
so plz know itWHAT??!!! I don't know anything like that?!!
a key point for mass spectrometry
if M and M+2 peaks are in ratio of 3:1 means chlorine is present
if M and M+2 peaks heights are in ratio of 1:1 than Bromine is in mixture (only one bromine)
if 2 Cl are included in mixture say Ch2Cl2Well said!!! I will stick to memorizing!
actually 35Cl is in 75% occuring in nature and 37Cl is 25% thats y ratio is 3:1is it going to be written in q that the ratio is this?????
hey thanks genious and good luck for papers
M will hav the highest ratio?!if 2 Cl are included in mixture say Ch2Cl2
u'll get peaks M (M+2)x2 and M+4
heights ratio 9:6:1
for br2 included u get 1:2:1 ratio
stay tune for y part
For the first question,[Fe(H2O)6-n(NO2)n]^2+ (n=1 to 6) how do we get this?
Q3 (D) why is that ketone getting reduced to -OH using Ni? ! M/J 2012 p41
ohhh...thanks i just realised my mistake...i was taking 'Fe' atom instead of ion so it cd only accommodate 4 ligands. Okay so is it necessary to include H2O whn such ques r asked or depends on....?!For the first question,
[Fe(H2O)6-n(NO2)n]^2+ (n=1 to 6) -----> simply means that if you have 2 NO2 ligands with Fe, then the H2O ligands will be 6-n = 6-2 = 4 H2O ligands. and the formula becomes ----> [Fe(H2O)4(NO2)2]^2+
n can be any number from 1 to 6, because Fe can only have a maximum of 6 ligands attached. There is a +2 charge on the entire complex because of the +2 charge on Fe - they don't exactly form a compound, it's a complex with dative bonds and the ligands donating a pair of electrons. Hope it's clear.
Yes, with Fe, H2O ligands are important to include.ohhh...thanks i just realised my mistake...i was taking 'Fe' atom instead of ion so it cd only accommodate 4 ligands. Okay so is it necessary to include H2O whn such ques r asked or depends on....?!
Thanks a ton! Stay blessed!
Can u gimme a few more examples for a) metal ions in which H2O is imp b) for which it aint imp.Yes, with Fe, H2O ligands are important to include.
