Explanation:
Organic compounds are defined as the compounds which contain carbon as their main element. For example, 
is an organic compound.
Generally, organic compounds are non-polar in nature and due to the presence of covalent bonding organic compounds have low melting point.
As compound A melts at 
and is soluble in water. This means it is an ionic compound as it has high melting point and it is also polar in nature.
Whereas compound B melts at 
and is insoluble in water. This means that this compound has covalent bonding and it is also non-polar in nature
. Hence, it is more likely to be organic in nature.
Thus, we can conclude that compound B is more likely to be an organic
compound.
Answer: The correct answer is option B.
Explanation: Reactivity of elements is defined as the tendency to loose or gain electrons.
These reactions are a type of single displacement reactions. A single displacement reaction is a type of reaction in which an element displaces another element in a chemical reaction. These are studied with the help of reactivity series.
The element which lies above in the reactivity series can easily displace the element which lies below in the reactivity series.
Option A: This reaction will not yield a stable product because Zinc lies below Aluminium in the reactivity series.
Option B: This reaction will yield a stable product because Sodium lies above Calcium in the reactivity series.
Option C: This reaction will not yield a stable product because Hydrogen lies below Magnesium in the reactivity series.
Option D: This reaction will not yield a stable product because Calcium lies below Barium in the reactivity series.
Option E: This reaction will not yield a stable product because barium lies below Lithium in the reactivity series.
