Answer:
Option-B (2-methylpropene)
Explanation:
The reaction scheme is attached below,
In first step the alkene acts a nucleophile and adds H⁺ across double bond yielding a stable tertiary carbocation.
In the second step the oxygen atom of methanol acts as nucleophile and attacks the positive charge carrying carbon atom resulting in the formation of t-butyl methyl ether.

Answer:
The correct answer is A. The oxygen atom has a negative charge.
Explanation:
because at the water molecule there is a covalent bond between Hydrogen atoms and Oxygen atom and in this bond the oxygen atom can attract the shared electrons more than the hydrogen atom , this result an unequal sharing of the electrons between the oxygen atom and the hydrogen atom , and this case that each molecule of water has oxygen atom with negative charge and two hydrogen atoms have positive charge
and answer D is wrong because the water called in chemistry the universal solvent , that because of its ability to solve many substance , and the substances which water cannot dissolve it is like oils and fat soluble at all
