Which is the correct formula for titanium (iii) oxide?

a. ti2o3
b. tio
c. ti3o2
d. ti2o4

The correct answer is Option A.

Explanation:

Titanium is the 22nd element of the periodic table with electronic configuration of

In the naming of the compound, the oxidation state of this element is given +3.

Oxygen is the 8th element of the periodic table with electronic configuration

This element will easily gain 2 electrons and shows an oxidation state of -2.  

By criss-cross method, the oxidation state of titanium and oxygen gets reversed and they form the coefficients of the compound.

The compound formed by the combination of Titanium(III) and oxygen is having chemical name of Titanium (III) oxide.

Thus, the correct answer is Option A.

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
