Have you heard of the term barometric pressure? What does it mean?
IRINA_888 [86]
<span>Barometric pressure is just the same as atmospheric pressure. It is called barometric pressure because the instrument used to measure is called barometer. It is the pressure exerted by the air at a certain altitude. Since it is the pressure exerted by the air, it is also known as the weight of the air above the Earth. Depending on the altitude at which the measurement is done, barometric or atmospheric pressure varies, but the barometric pressure at sea level is 1 atm (atmosphere). It is equivalent to 101325 Pa (Pascal), 760 torr, 760 mm Hg and 1.01325 bar.</span>

Newman projections are given for two of the conformers of 2-methylbutane, drawn as viewed down the C2-C3 bond. In A the _____ st
schepotkina [342]

The Newman projection gives the view of the molecule. In molecule A the torsional strain and in B steric strain are present because of the gauche methyl group.

<h3>What is a torsional strain?</h3>

The Newman projection depicts the molecules in the head-on view and uses the letters and the lines to represent the molecule. The torsional strain is because of the molecule's resistance to the twisting.

The steric strain is the Vander wall strain that is due to the forced interaction of the molecules separated by covalent bonds resulting in molecular potential energy.

The diagram for the question is attached below.

Therefore, the correct blanks are <u>torsional</u>, <u>steric</u>, and <u>gauche</u>.
