Question 5

What is Mez spectrometry used for?

Answer 5

To determine molecular formula of a compound?

Question 6

Which peak is the same as the MR

Answer 6

The peak with the highest mass ratio

Question 7

When does an M and M +2 peak occur?

Answer 7

It occurs due to the two naturally occurring isotopes of chlorine or bromine

Question 8

What absorbs infrared radiation at different numbers?

Answer 8

Bones in a molecule absorb radiation at characteristic wavelength

Question 9

What is fingerprinting?

Answer 9

They allowed identification of a molecule by comparison of a spectra. This is done by using the data sheet to identify particular bonds and functional groups.

Question 10

What is the mechanism of the greenhouse effect?

Answer 10

UV Waveland radiation will pass through the atmosphere to the earths surface and heat up the earthssurface the earth will radiate out infrared long Waveland radiation. The c double bond o absorbs infrared radiation so that it doesn’t escape from the atmosphere
This energy is transferred to other molecules in the atmosphere by collision so that the atmosphere is warmed
