Assertion : Addition of HBr on 2-butene gives two isomeric products.
Reason: Addition of HBr on 2-butene follows Markovnikov's rule.
If both assertion and reason are true and reason is the correct explanation of the assertion.
If both assertion and reason are true but reason is not the correct explanation of the assertion.
If assertion is true, but reason is false.
Both assertion and reason are false statements.
The pair in which both species have same magnetic moment (spin only value) is
[Cr(H2O)6]2+,[CoCl4]2+
[Cr(H2O)6]2+,[Fe(H2O)6]2+
[Mn(H2O)6]2+, [Cr(H2O)6]2+
[CoCl4]2-, [Fe(H2O)6]2+
B.
[Cr(H2O)6]2+,[Fe(H2O)6]2+
Spin only magnetic moment, where n= number of unpaired electrons. Number of unpaired electrons in Cr2+ ([Ar] 3d4) is 4, in Co2+ ([Ar] 3d7) is 3, Fe2+([Ar]3d6) is 4, in Mn2+([Ar]3d5) is 5.
The incorrect statement among the following is
C60 is an allotropic form of carbon
O3, is an allotropic form of oxygen
S8 is only allotropic form of sulphur
red phosphorus is more stable in air than white phosphorus.
Given below, catalyst and corresponding process/ reaction are matched. The mismatch is
[RhCl(PPh3)2] : Hydrogenation
TiCl4+ Al(C2H5)3 : Polymerization
V2O5 : Haber-Bosch process
nickel : Hydrogenation.
Tincture iodine is
aqueous solution of I2
solution of I2 in aqueous Kl
alcoholic solution of I2
aqueous solution of Kl.
