2) from the spectral data (nmr, ir, ms) you were given, identify the structure of your ester product.
3) based on your answer to q2, what is the structure of your starting alcohol?
4) assign the major peaks in the ir spectrum of your product.
5) fully assign the 1 h nmr spectrum of your product (i. e. determine which peaks in the 1 h nmr correspond to which hydrogens in the product). you will not receive full marks for determination of the unknown unless you assign the 1 h nmr spectrum completely.
6) you will notice that we gave you the m/z value of the m+ ion of your product on the ei (electron impact) mass spectrum, but the actual peak on the spectrum is very small (or even non-existent). read mcmurry p426-432 (especially p431) and explain why the m+ peak is so small

b. examine and describe cells

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
