Give the structures of both 1,2 and 1,4 adducts resulting from reaction of 1 equivalent of hcl with 1,3-pentadiene

Chemistry
1 answer:
GrogVix [38]3 years ago
3 0

1,3-pentadiene has two double bonds which are conjugated, which undergo electrophilic addition reaction on reacting with HCl.

The structure of 1,3-pentadiene is shown in the image.

When strong acid such as HCl reacts with 1,3-pentadiene, the electrophilic addition reaction can occur either on double bond at 1,2-position or at 3,4-position. The reaction that occurs is shown in the image.

The The thermal conductivity of a sheet of rigid, extruded insulation is reported to be k=0.029 W/ m measured temperature differ
vfiekz [6]

Answer:

Heat flux = 13.92 W/m2

Rate of heat transfer throug the 3m x 3m sheet = 125.28 W

The thermal resistance of the 3x3m sheet is 0.0958 K/W

Explanation:

The rate of heat transfer through a 3m x 3m sheet of insulation can be calculated as:

q=-k*A*\frac{\Delta T}{\Delta X}\\\\q=-0.029\frac{W}{m*K}*(3m*3m)*\frac{12K}{0.025m}  =125.28W

The heat flux can be defined as the amount of heat flow by unit of area.

Using the previous calculation, we can estimate the heat flux:

heat \, flux=\frac{q}{A}=\frac{125.28 W}{9 m^{2} }  =13.92 W/m^{2}

It can also be calculated as:

q/A=-k*\frac{\Delta T}{\Delta X}

The thermal resistance can be expressed as

\Delta T=R_t*Q\\R_t=\Delta T/Q=\frac{\Delta X}{k*A}

For the 3m x 3m sheet, the thermal resistance is

R_t = \frac{\Delta X}{k*A}=\frac{0.025m}{0.029W/mK*9m^{2}}=0.0958 \, K/W

What is the molarity when water is added to 4 moles of sodium chloride to make 0.5 liter of solution?
loris [4]
       If    0.5 L of solution contains 4 mol
then let     1 L of solution contain  x  mol
      
       ⇒    (0.5 L) x  = (4 mol) (1 L)

                         x  = (4 mol · L)  ÷  (0.5 L)

                         x  = 8 mol

Thus the molarity of the Sodium Chloride solution is 8 mol / L   OR  8 mol/dm³.
