Why do valence electrons form bonds to create molecules and compounds?

Chemistry

Ksju [112]3 years ago
3 0

Valence electrons form bonds to create molecules and compounds because A. they are weaker than the electrons found closer to the nucleus.

A better way of saying it is that the valence electrons are <em>less strongly attracted</em> to the nucleus.

All electrons have the same size, but the <em>orbitals</em> they occupy have different sizes.

A car's fuel efficiency is 39.0 miles per gallon. What is its fuel efficiency in kilometers per liter? (1.6094 km=1 mile)(1 gall
MrRa [10]

Answer:

the fuel efficiency in kilometers per liter is 16.561 kilometer per liter

Explanation:

The computation of the full efficiency in kilometers per liter is shown below:

39.0 miles ÷ gallon = (39.0 miles ÷ gallon) × (1.6094 km ÷ 1 miles)  × (1 gallon ÷ 3.79 L)

Now cut the opposite miles and gallons

So, the fuel efficiency would be

= 16.561 kilometers per liter

Hence, the fuel efficiency in kilometers per liter is 16.561 kilometer per liter

Draw the major product that is formed when 2-butyne is treated with an excess of hydrogen gas and a platinum catalyst. draw the
trasher [3.6K]

Answer:

Addition of hydrogen in unsaturated hydrocarbons is known as Hydrogenation.

Major product that is formed when 2-butyne is treated with an excess of hydrogen gas and a platinum catalyst is an alkane of four carbon atom known as butane.

Here hydrogen gas is in excess, first but-2-ene will form from the but-2-yne then butane will form from the but-2ene.

1) CH_3-CH\equiv CH-CH_3\overset{H_2/Pt}\rightarrow CH_3-CH=CH-CH_3

2) CH_3-CH=CH-CH_3\overset{H_2/Pt}\rightarrow CH_3-CH_2-CH_2-CH_3

As shown in the image attached.
