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

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

a polar bond is formed when electrons are shared unevenly between atoms

the awnser is group 12

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
