Show how you might synthesize this compound from an alkyl bromide and a nucleophile in an sn2 reaction. use the wedge/hash bond tools to indicate stereochemistry where it exists. only draw the reactants. separate multiple reactants using the + sign from the drop-down menu. if there is more than one possible combination of alkyl bromide and nucleophile, draw only one combination. do not include counter-ions, e. g., na+, i-, in your answer.

explanation:

the marks go by 4s

(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
