A) Mention any two properties of an ideal fuel. (b) What is meant by calorific value? (c) 2kg of a fuel produces 48,000 KJ of he
Brilliant_brown [7]

Answer and explanation:

A) An ideal fuel must:

- easy to transport and storage.

- have a high calorific value.

B) The <em>calorific value</em> for a fuel is the amount of heat - measured in Joules- which is produced during the complete combustion of the fuel. It is expressed in Joules per Kg of fuel (J/kg).

C) From the data:

mass of fuel = 2 kg

heat produced = 48,000 KJ

We calculate the calorific value by dividing the heat produced by the mass of fuel, as follows:

calorific value = heat produced/mass of fuel = (48,000 KJ)/(2 kg)= 24,000 kJ/kg

Since 1 KJ= 1000 J, we can express the calorific value in J/kg as follows:

24,000 kJ/kg x 1000 J/1 kJ = 2.4 x 10⁷ J/kg

Design a synthesis of 2-bromo-1-chloro-4-nitrobenzene from benzene or any mono-substituted benzene. Part 1 out of 6 choose the b
Oxana [17]

2-bromo-1-chloro-4-nitrobenzene  is being synthesized in following sequence:

Step 1: Chlorination of Benzene:

                                                     This is Halogenation reaction of benzene. In this step benzene is reacted with Chlorine gas in the presence of lewis acid (i.e. FeCl₃). This results in the formation of Chlorobenzene as shown in red step below.

Step 2: Nitration of Chlorobenzene:

                                                          The chlorine atom on benzene has a ortho para directing effect. Therefore, the nitration of chlorobenzene will yield para nitro chlorobenzene as shown in blue step below.

Step 3: Bromination of 1-chloro-4-nitrobenzene:

                                                                               In this step bromination is done by reacting bromine in the presence of lewis acid. The chlorine being ortho para directing in nature and nitro group being meta directing in nature will direct the incoming Br⁺ (electrophile) to the desired location. Hence, 2-bromo-1-chloro-4-nitrobenzene is synthesized in good yield.

Gaseous BF3 and BCl3 are mixed in equal molar amounts. All B-F bonds have about the same bond enthalpy, as do all B-Cl bonds. Co
lord [1]

Solution :

$BF_3 (g) + BCl_3 (g) \rightarrow BF_2 Cl + BCl_F(g)$

<u>Explanation 1 </u>:

Spontaneity of the reaction is based on two factors :

-- the tendency to acquire a state of minimum energy

-- the energy of a system to acquire a maximum randomness.

Now, since there isn't much difference in the bond enthalpies of B-F and B-Cl. So, we can say the major driving factor is tendency to acquire a state of maximum randomness.

<u>Explanation 2 </u>:

A system containing the \text{"chemically mixed"} B halides has a \text{greater entropy} than a system of $BCl_3$ and BF_3.

It has the same number of \text{gas phase molecules}, but more distinguishable kinds of \text{molecules}, hence, more microstates and higher entropy.
