Construct a simulated 1H NMR spectrum for methyl propanoate by dragging and dropping the appropriate splitting patterns into the boxes on the chemical shift baseline, and by dragging integration values into the small box above each signal. Items may be used more than once. Peak heights do not represent integration.

Explanation:

The attached file shows the HNMR of methyl propanoate. The hydrogen atoms on the CH3 attached to the CH2 have a chemical shift of 1.14 being in the same chemical environment. The hydrogen atoms on the CH2 have the same chemical shift of 2.29 being in the same chemical environment and close to the COO group. The hydrogen atoms on the CH3 attached to the COO group have the highest chemical shift of 3.67, being very close to the electronegative element (i.e Oxygen).

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
