Answer:
Enolate Alkylation
The anions from ketones, called enolates, can act as a nucleophile in SN2 type reactions. Overall an α hydrogen is replaced with an alkyl group and a new carbon-carbon bond is formed. These alkylations are affected by the same limitations as SN2 reactions previously discussed. A good leaving group, chloride, bromide, iodide or tosylate, should be used. Also, secondary and tertiary leaving groups should not be used because of poor reactivity and possible competition with elimination reactions. Lastly, it is important to use a strong base, such as LDA or sodium amide, for preparing the enolate from the ketone. Using a weaker base such as hydroxide or an alkoxide leaves the possibility of multiple alkylations occurring, and competing SN2 reactions with the base.

Answer:
<h2>1. Ionic compound-Explanation:
Mg is a metal that has 12 atomic numbers and thus its electronic configuration is . The outer most shell of this element has 2 electrons so it loses 2 electrons and thus form
ions. Br is a nonmetal and has 35 atomic number so its electronic configuration is
. Since its outermost shell has 7 electrons so it can accept one electron and thus forms
. So magnesium ion and bromide ion combine and forms an ionic compound
.
P is also a nonmetal and combine with Br with covalent bond and due to electronegativity differences form polar covalent compound such as .
