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+
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.
The colour imparted by Co(II) compounds to glass is
green
deep-blue
yellow
red
B.
deep-blue
Glass is an amorphous and transparent or translucent solid obtained by solidification of a mixture of silicates of different metals, one of which is always an alkali metal. Addition of small amounts of transition metal salts to the glass mixture imparts colour to the glass. For example, addition of small amounts of Fe3+,Fe2+ ,Co2+ ,Cr3+and Mn4+ salts imparts yellow-brown, light blue, deep blue, green or violet colour respectively.
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.
