Why oxygen shows hydrogen bonding where as chlorine do not ? even though the electronegativity of these are nearly same.

Electron density is the main reason behind this. In case of oxygen the size is smaller and electroneagativity is high. Due to this the electron density is high in case of oxygen. but in case of chlorine , the size of chlorine being larger, distributes the electrons in larger field and this decreases the electron

Oxo-acids of sulphur

Here is the list of oxo-acids of sulphur :- (i) Thiosulphuric Acid – H2S2O3 (ii) Pyrosulphuric Acid – H2S2O7 (iii) Thiopersulphuric Acid – H2S2O4 (iv) Sulphuric Acid – H2SO4 (v) Peroxodisulphuric Acid – H2S2O8 (vi) Sulphurous Acid – H2SO3 (vii) Peroxomonosulphuric Acid – H2SO5 (viii) Dithiopersulphuric Acid – H2S2O5

Why Perchloric acid is stronger than sulphuric acid ?

The strength of an acid depends upon the oxidation state of the central atom. More is the oxidation state higher is the acidic character. In case of HClO4(perchloric acid) the oxidation state of chlorine is +7. And in case of H2SO4 (sulphuric acid) the oxidation state of Sulphur is +6 . The oxidation state of

An organic compound of carbon, hydrogen and nitrogen contains elements having a mass percentage of 66.67%, 7.41% and 25.92%, respectively. What is the empirical formula?

Step 1 : Assume the percentage as grams and divide it with molar mass. Step 2: By this way you have calculated the number of moles , further divide evey term with the smallest term which you have calculated in step 1. Step 3 : Now you have the simple whole number ratio of elements

Why Carboxylic Acids are more acidic than phenols ?

In case of carboxylic acids the negative charge is on the more electronegative element that is oxygen as shown in the structure in both of the resonating structures. The negative charge on the more electronegative element makes it more stable. And thus it shows acidic character easily. But in case of phenols the negative charge
