Pick the odd one out from the following. Milk, Butter, Smoke , Carbon dioxide
1.Milk
2.Carbon dioxide
3. Smoke
4.Butter
plz answered fast

Smoke

Explanation:

All of those listed are under the group of matter, except for smoke, making it the odd one one.

The rough definition of matter means that it occupies space, but smoke does not.

There are 3 main groups, Solid, Liquid and Gas.

Milk is classified under liquid.

Carbon Dioxide is classified under gas.

Butter is classified under solid.

Since you cannot classify smoke under any of the 3 categories, it is the odd one out.

lol for the pointsss

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.
