Which of the following is wrong statement?
Ni(CO)4 has oxidation number +4 for Ni
Ni(CO)4 has zero oxidation number for Ni
Ni is metal
CO is gas
CH3C(CH2CH3) = CH(CH3) X. No. of optical isomer possible will be
2
4
0
3
A.
2
When A reacts with hydrogen in presence of a catalyst the following reaction is observed,
The product formed is in both d and l form. Therefore, two optical isomers are possible.
H2C2O4 + KMnO4 in acidic medium reacts to have change in oxidation number of Mn from
7 to 5
2 to 7
5 to 7
7 to 2
Frenkel and Schottky defects are
nucleus defects
non-crystal defects
crystal defects
nuclear defects
