Rank the compounds in each set in order of increasing acid strength.
Viktor [21]

Answer:

See explanation

Explanation:

For this question, we have to remember the effect of an atom with high <u>electronegativity</u> as "Br". If the "Br" atom is closer to the carboxylic acid group (COOH) we will have an <u>inductive effect</u>. Due to the electronegativity of Br, the electrons of the C-H bond would be to the Br, then this bond would be <u>weaker</u> and the compound will be more acid (because is easier to produce the hydronium ion H^+).

With this in mind, for A in the last compound, we have <u>2 Br atoms</u> near to the acid carboxylic group, so, we will have a high inductive effect, then the C-H would be weaker and we will have <u>more acidity</u>. Then we will have the compound with only 1 Br atom and finally, the last compound would be the one without Br atoms.

In B, the difference between the molecules is the <u>position</u> of the "Br" atom in the molecule. If the Br atom is closer to the acid group we will have a <u>higher inductive effect</u> and more <u>acidity</u>.

See figure 1

I hope it helps!

Answer:

Waterwould be the best choice

Explanation:

<em>The specific heat capacity</em> refers to how much energy is required to raise the temperature of an object. The higher the specific heat capacity, the more energy is required to heat a given substance. This would also mean that w<u>ith a higher specific heat capacity, a substance would be able to retain more heat</u>.

With the above statements in mind, water would be the best choice, because it would retain more heat than the other substances once it reaches 100 °C, and in turn water would emit the most heat while it cools.

One oxygen atom shares two electron with two hydrogen atoms in this way water molecules are formed. The bond between oxygen and hydrogen is covalent bond.

<h3>What is covalent bond ?</h3>

An electron exchange that results in the formation of electron pairs between atoms is known as a covalent bond. Bonding pairs or sharing pairs are the names given to these electron pairs.

Covalent bonding is the stable equilibrium of the attractive and repulsive forces between atoms when they share electrons.

According to the amount of shared electron pairs, there are three different forms of covalent bonds. single covalent bond is one type of covalent bond. covalent double bond and covalent triple bond.

Thus, option B is correct .
