32. The dissociation energy of CH4 (g) is 360 kcal mol-1 and that of C6 H6 (g) is 620 kcal mol-1. The C-C bondenergy is(1) 260 kcal mol-1 (2) 180 kcal mol-1(3) 130 kcal mol-1 (4) 80 kcal mol-1​ plz give answer it's urgent...

Answer»

We are given dissociated energy of CH4 = 360 Since,  has 4 CH bonds.Dissociated energy of 1 CH bond = 360 ÷ 4 = 90 The dissociation energy of  = 620 Where  has 1 C-C bond and 6 CH bonds.  So, we can calculate the dissociated energy of 1 C-C bond by:C-C bond + 6CH bond = 620C-C bond + (6 × 90) = 620C-C bond + 540 = 620C-C bond = 620 - 540 = 80 Explanation:

How to identify which is "acid"and which is "base"​

Answer»

tify whether the substance is acid or base it can be DONE by following :- USING LITMUS paper or natural indicator. By their TASTE if the substance is sour in taste than it is acid and if it is bitter than it is base.Checking pH value if the pH value is more than 7 than it is basic in nature if the pH value if less than 7 than it is acidic.Acid donate Hydrogen ion WHEREAS Bases donate Hydroxide ion.

1. Why alkyl halides are generally not prepared in the laboratory by free radical halogenation of alkanes?​

Answer»

The answer is simple because in free radical halogenation we get a mixture of mono-substituted, di-substituted, tri-sunstituted and even tetra-substituted halo-alkanes (alkyl HALIDES).EXPLANATION:Refer to the PIC (I am attaching) which shows the free radical halogenation of chlorine that gives a variety of products (as we REQUIRE only one type alkyl HALIDE not all in the form of mixture THUS we does not use this method)

When photons of energy 4.25 eV strike the surface of a metal A, the ejected photoelectrons have maximum kinetic energy, T1 (expressed in eV) and de-Broglie wavelength lambda2. The maximum kinetic energy of photoelectrons liberated from another metal B by photons of energy 4.20 eV is T2 -T1 = 1.50eV. If the de Broglie wavelength of these photoelectrons is 2lamda= 2×lambda1 then which is not correct :1) The work function of A is 2.25 eV2) The work function of B is 3.70 eV3) T1 = 2.00eV4) T2= 2.75 eV​

Definition of baseberg theory​

Answer»

Three principal theories about acid-base are,1. Arrhenius theory2. Bronsted-Lowry theory3. Lewis theoryAccording to the Arrhenius, acids give up hydrogen ion in aqueous medium and a base give up hydroxyl ion in its aqueous medium. Examples are aqueous solution of HCl, CH3COOH, PhCOOH, and H2SO4. These give up H+ in an aqueous medium. Aqueous solutions of NaOH, Ca (OH)2 are Arrhenius bases.Arrhenius theory has some limitations. This theory cannot explain the acidic nature of BF3 or basic behavior of NH3. This theory FAILS to give any explanation about acidity and basicity which does not produce H+ and OH- in their aqueous solutions.According to the Bronsted-Lowry, an acid releases proton and a base accepts proton. NH3 accepts proton and forms ammonium ion, so ammonia acts as a base.But this theory also has limitations. According to this theory acidic behavior of BF3 STILL cannot be explained.According to the Lewis theory, acids are those substances which accept electron pair and base are those substances which DONATES electron pairs. Lewis theory can explain the acidic nature of BF3. In BF3, B is TWO electrons short to fulfil its octet. So it can accept a pair of electrons from an electron donating substituent. So it is an electron pair acceptor compound and acts as an acid.Substances which have π electrons can donate electron pair to an electron deficient substance and acts as a base. Ethylene and acetylene is Lewis bases. AlCl3, PCl3 are Lewis acids.Hope you like the answer.................

Fundamental Rights are meant for promoting the idea of democracy.Originally the constitution provided 7 Fundamental Rights but as of now there are just 6 Fundamental Rights in force. They are;1. Rights to equality (Article 14-18)2. Rights to freedom (Article 19-22)3. Right against EXPLOITATION (Article 23-24)4. Right to freedom of religion (Article 25-28)5. Cultural and educational rights (Article 29-30)6. Rights to CONSTITUTIONAL remedies (Article 32).
