Answer:

Total 8 electrons.

Explanation:

To draw a complete lewis structure in water molecule we will calculate the total number of valence electrons

Valence electrons:

Two hydrogen atoms: 2 valence electrons (one each)

One oxygen atom : 6 valence electrons

So total there will be 8 electrons that must be shown in the structure.

Out of these 8, four will be involved in two covalent bonds

Rest four will be in the form of two lone pair of electrons on oxygen atom.

In the Lewis structure, each single bond drawn between elements contain two electrons. The electron dots represent the lone pairs. These are the electrons that take part in the reaction. To obey the octet rule, the oxygen must have eight electrons around it. The hydrogen is exempted from this rule. Therefore, you have to show two electrons.

Answer:

See figure 1

Explanation:

On this case we have a base (methylamine) and an acid (2-methyl propanoic acid). When we have an acid and a base an acid-base reaction will take place, on this specific case we will produce an ammonium carboxylate salt.

Now the question is: ¿These compounds can react by a nucleophile acyl substitution reaction? in other words ¿These compounds can produce an amide? 

Due to the nature of the compounds (base and acid), the nucleophile (methylamine) doesn't have the ability to attack the carbon of the carbonyl group due to his basicity. The methylamine will react with the acid-producing a positive charge on the nitrogen and with this charge, the methylamine loses all his nucleophilicity.
