Which of the following is not a compound?
1 Marble
2 Ozone
3 Carborundum
4 Quicklime
Explanation:
Ozone \({\rm{(}}{{\rm{O}}_{\rm{3}}}{\rm{)}}\) consists of only one kind of atom oxygen. The structure formed by only one type of atom is called a molecule not compound. A compound is a combination of more than one element. Marble, \({\rm{CaC}}{{\rm{O}}_{\rm{3}}}\) is made by the combination of calcium, carbon and oxygen. Carborundum, \({\rm{SiC}}\) is a compound and quicklime, \({\rm{CaO}}\) is also compound.

Which of the following sets of components form homogeneous mixture?
1 Phenol + Water
2 Sugar + Benzene
3 Silver chloride + Water
4 Ethyl alcohol + Water
Explanation:
Phenol + water and ethyl alcohol + water both forms homogeneous mixture but homoge neousily of Ethyl alcohol + water is more as compared to phenol + water (larger alkyl group). Thus, the correct option is ‘4’.

Assertion : Element and compound are the examples of pure substances. Reason : Element contains one kind of atoms while a compound contains more than one kind of elements or atoms.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Elements are fundamental pure substances with distinct properties, indivisible by chemical or physical processes, while compounds are also pure substances formed by combining two or more elements in fixed proportions. So, the option (2) is correct.
