The name of the given molecule according to IUPAC is 1-Butyne. Thus, option C is correct.

<h3>What is IUPAC nomenclature?</h3>

The IUPAC nomenclature is given as the standard naming technique that is used to name a chemical compound. It is named with the following main rules.

The triple bond compound is an alkyne with the suffix -yne. The development of the name to the given structure is therefore given by counting the number of carbon atoms, and the location of the triple bond.

There are 4 carbon atoms in the structure with the triple bond at carbon 1, therefore the name will be 1-Butyne. Hence, option C is correct.

Answer:

(iii) A has pH greater than 7 and B has pH less than 7

Explanation:

Phenolphthalein is a common indicator in acid base titrations. It turns pink in basic conditions and turns colorless in acidic conditions. Thus on addition of solution A it becomes pink so A should be basic having pH more than 7. On addition of B , it turn out to be colorless means that B is an acidic solution having pH less than 7.

How many liters of 1.5 M potassium permanganate could be made if 152 g of the solute are available?

Misha Larkins [42]

Answer:

0.64 L

Explanation:

Recall that

n= CV where n=m/M

Hence:

m/M= CV

m= given mass of solute =152g

M= molar mass of solute

C= concentration of solute in molL-1 = 1.5M

V= volume of solute =????

Molar mass of potassium permanganate= 158.034 g/mol

Thus;

152 g/158.034 gmol-1= 1.5M × V

V= 0.96/1.5

V= 0.64 L

Part A

KonstantinChe [14]

Answer:

The answer to your question is below

Explanation:

[H₃O⁺] = 2 x 10⁻¹⁴ M

pH = ?

Formula

pH = - log [H₃O⁺]

Substitution

pH = - log [2 x 10⁻¹⁴]

Result

pH = 13.7

[H₃O⁺] = ?

pH = 3.12

Formula

pH = - log [H₃O⁺]

Substitution

3.12 = - log [H₃O⁺]

$10^{-3.12} = [H_{3} O^{+}]$

Result

[H₃O⁺] = 7.59 M
