What is the wavelength of a 2500 kg truck traveling at a rate of 75km/h?

Pepsi [2]

m = mass of the truck traveling = 2500 kg

v = speed of the truck traveling = 75 km/h = 75 (km/h) (1000 m/ 1 km) (1 h /3600 sec) = 20.83 m/s

h = plank's constant = 6.63 x 10⁻³⁴

λ = wavelength of truck = ?

according to de broglie's principle, wavelength of truck is given as

λ = h/(mv)

inserting the values in the above equation

λ = (6.63 x 10⁻³⁴)/((2500) (20.83))

λ = 1.3 x 10⁻³⁸ m

Which of the following is the requirement for the intramolecular Sn2 reaction (intramolecular William Ether Synthesis) to occur

balandron [24]

Answer:

D. Anti-periplanar

Explanation:

In the second step of the intramolecular William Ether Synthesis mechanism (figure 1) we will have the attack of the negative charge of the oxygen to the carbon bond to the Br. At the same time the Br leaves, so a bond would be broken (the C-Br bond) and a bond would be formed (the C-O bond).

Now, this process can happen only if the attack and the leaving group has an anti configuration (figure 2). In an anti configuration the nucleophile and the leaving group would have opposite directions.
