Question

Select the incorrect statement from the following option.

(a) TMS stands for tetra methyl silane

(b) All the hydrogen in TMS have the same chemical shift

(c) TMS has a high boiling point, so it is not easily lost when holding the NMR sample

(d) TMS is relatively unreactive with most functional groups

I got this question during a job interview.

I would like to ask this question from Nuclear Magnetic Resonance topic in chapter Absorption Spectroscopy of Engineering Chemistry I

Answer 1

The correct answer is (c) TMS has a high boiling point, so it is not easily lost when holding the NMR sample

To elaborate: TMS has a low boiling point so it can be easily removed from a recoverable sample of an organic compound. All the other options are correct. TMS is relatively unreactive with most functional groups.
