Answer: Difference in properties of these two compounds are because one compound is covalent and the other one is ionic.
Explanation: LiCl is an inorganic compound having high electronegativity difference between the two elements and hence, is termed as an ionic compound.
is a organic compound formed by the sharing of electrons between the elements, hence is termed as a covalent compound.
Hence, the properties are different because one of the compound is covalent and other is ionic.
Answer: Option (B) is the correct answer.
Explanation:
Elements of a group represent similar chemical properties because they contain same number of valence electrons which determines their reactivity.
Hence, elements of a group have same chemical nature or property.
A group is represented by a vertical column in a periodic table.
On the other hand, a period is represented by a horizontal line.
Thus, we can conclude that a column contains elements with similar properties in the periodic table.
