1.) N3Cl
2.) Ionic because Cs is a metal and PO4 is a nonmetal
The name of the compound is Thorium (IV) Iodide and formula of the compound ThI₄.
<h3>What is Molecular Formula ?</h3>
The chemical formula that gives total number of atoms of each element in one molecule of a compound is called Molecular Formula.
<h3>What is Atomic Number ?</h3>
The number of proton which is used to separate one element from the other element is called Atomic Number.
here the atomic of the element Q is 90 and the atomic number of R is 53. The element Q is Thorium. Symbol of Thorium is Th. The element R is Iodine. Symbol of Iodine is I.
The valency of thorium is +4 and valency of Iodine is -1. So the formula of the compound is ThI₄.
Thus from the above conclusion we can say that The name of the compound is Thorium (IV) Iodide and formula of the compound ThI₄.

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.
