Draw the structure of 2 methyl,but-3-ene
Maslowich

Answer:

Please find the structure attached as an image

Explanation:

Based on the characteristics ending name (-ene) of the organic compound above, it belongs to the ALKENE GROUP. Alkenes are characterized by the possession of a carbon to carbon double bond (C=C) in their structure.

- But-3-ene tells us that the organic compound has four straight carbon atoms with the C=C (double bond) located on the THIRD carbon depending on if we count from right to left or vice versa.

- 2 methyl indicates that the methyl group (-CH3) is located as an attachment on the second carbon (carbon 2).

N.B: In the structure attached below, the counting is from the left to right (→).

How do chemical weathering and physical weathering affect each other?
Zinaida [17]
Both processes occur in place. No movement is involved in weathering. Chemical weathering involves a chemical change in at least some of the minerals within a rock. Mechanical weathering involves physically breaking rocks into fragments without changing the chemical make-up of the minerals within it.

1. A high surface tension and a high boiling point both indicate that there
enyata [817]

The liquid that is expected to have the weakest intermolecular interaction is the liquid that has the lowest boiling point and surface tension.

<h3>What is boiling point?</h3>

The term boiling point refers to the temperature at which the atmospheric pressure and the pressure of the liquid becomes equal. The greater the intermolecular forces of attraction between molecules the higher the boiling point of the solid. Also a high surface tension indicates a strong  intermolecular forces of attraction between molecules.

The liquid that is expected to have the weakest intermolecular interaction is the liquid that has the lowest boiling point and surface tension.
