When ortho-bromonitrobenzene is treated with NaOH and heat one
product is formed.
a) show the mechanism
b) would the reaction occur if starting material was
para-bromotoluene
c) would the reaction occur if starting material was
meta-bromotoluene
When 1-‐iodo-‐1-‐methylcyclohexane is treated with NaOCH2CH3
as the base, the more highly substituted alkene product
predominates.When KOC(CH3)3 is used as the base, the less highly
substituted alkene predominates. Give the structures of the two
products and offer an explanation.
2500 mol/min of a liquid stream containing 1% component B is to
be treated by stripping with air. The incoming air contains 0.01%
B, and the liquid leaving the stripper is to contain 0.01% B. The
Henry’s law constant is 1.5.
a. What is the minimum required gas rate?
b. If the gas rate is 1.15 times the minimum gas rate, how many
theoretical stages are required?
What is the predominant intermolecular force in the liquid state
of each of these compounds: ammonia (NH3), carbon tetrachloride
(CCl4), and hydrogen sulfide (H2S)? Drag the appropriate items to
their respective bins.
1. 1-methyl-1,2-epoxycyclohexane treated with 1) CH3MgBr and 2)
H20 provides what product?
2. 1,5-epoxypentane treated with EXCESS HI provides what
product?
Vapor Pressures of a solid and liquid ammonia near the triple
point are given by: log P solid/ torr=10.00-1630 K/T log P liquid /
torr=8.46-1330 K/T Calculate the ratio of the slopes of the
sublimation and vapor pressure curves at the triple point.
A steel storage tank 20m in diameter will be used to hold liquid
petroleum product. When filled, the tank causes a bearing pressure
of 150kPa. The soil underlying the tank has a unit weight of
16.5kN/m3 above the water table and 19.8kN/m3 below the water
table. For a depth of 10m below the base of the tank, compute the
effective vertical stress when the tank is empty and when it is
full, for points under the center and the edge....
14) Suppose a low-boiling liquid like ammonia is placed in a
heat reservoir and part of the energy of the surroundings is used
to vaporize the liquid.The adiabatically expanding gas does work by
driving a piston and during the expansion the gas cools until it
condenses to a liquid, the liquid is once again vaporized using
energy available from the surroundings, and the cycle is repeated.
Can such an engine be made operational?
