Answer:
See image attached for structure of CH3Br
Explanation:
A lewis structure structure is a representation of a covalent compound in which dots are used to show valence electrons, lone pairs and bonding electrons. The system was introduced by sir G.N Lewis in 1916 in his article titled 'Atom and Molecule'. They are also called dot electron diagrams of molecules. CH3Br molecule contains a total of fourteen electrons. Valence electrons are shown by dots around the atom of each element as clearly seen in the image attached.
Concentrated sulfuric acid is used to promote acid catalyzed dehydration because it has little water.This favor the forward reaction.sulfuric acid acts as as proton source to enable loss of leaving group in forward reaction and electrophile addition in reverse reaction.
Liquid, solid, and gas are all different substances
