Freidal craft reaction is the attack of a carbon or carbon chain on aromatic ring with the help of anhydrous AlCl3 to produce alkylated benzene ring.

Only ketone not be able to undergo friedal craft reaction as, it is not aromatic compound whereas all the given reactants are aromatic and gives friedal craft reaction.

For the following list of acids, rank the acids in strength from weakest acid to strongest acid.
-BARSIC- [3]

Answer:

CH3OH < FCH2OH < F2CHOH < F3COH

Explanation:

Let us recall that, for a carboxylic acid, the dissociation of the acid yields;

RCOOH ⇄RCOO^- + H^+

The ease of dissociation and release of the hydrogen ion depends on the nature of the group designated R.

When R is is a highly electronegative element, the -I inductive effect causes the hydrogen to become less tightly held by the C-Cl bond.

As the number of electron withdrawing substituents increaseses, the acid ionizes much more and becomes stronger.CH3OH < FCH2OH < F2CHOH < F3COH

Hence, the order of decreasing acid strength is;

How much time will you save on a ten mile trip if u travel at 60mph rather than at 55mph?
elena-14-01-66 [18.8K]

Time = Distance/Rate

for 60 mph

Time = 10 miles/60 mph

= 0.1666 * 60 minutes = 10 minutes

for 55 mph

Time = 10 miles/55 mph

= 0.181818 * 60 minutes = 10.90 minutes

Which of the following molecules has/have the same empirical formula as acetic acid (HC2O2H3)? (a) Formaldehyde (b) Benzaldehyde
chubhunter [2.5K]

Answer: Option (a) is the correct answer.

Explanation:

A chemical formula which represents proportions between the elements present in a compound is known as empirical formula.

When chemical or molecular formula is able to be reduced to smaller whole-number ratio of the elements then both molecular and empirical formulas are considered to be the same.

Relation between molecular formula and empirical formula is as follows.

               Molecular formula = n × Empirical formula

where, n is an integer.

Chemical formula of acetic acid is CH_{3}COOH.

Chemical formula of formaldehyde is CH_{2}O. It is the smaller whole-number ratio of molecular formula of acetic acid.

Chemical formula of Benzaldehyde is C_{6}H_{5}COOH.

Chemical formula of glucose is C_{6}H_{12}O_{6}.

Thus, we can conclude that formaldehyde molecules has/have the same empirical formula as acetic acid (HC_{2}O_{2}H_{3}).

Molecular bromine is 24 percent dissociated at 1600 k and 1.00 bar in the equilibrium br2 (
dlinn [17]
Br2 == 2Br

24% dissociated => n total moles, 0.24 mol*n of Br, and 0.76*n mol of Br2

=> partial pressure of Br, P Br = 0.24 bar, and
     partical pressure of Br2, P Br2 = 0.76 bar

kp = (P Br)^2 / P Br2 = (0.24)^2 / 0.76 = 0.0758
