The E.N. of H,X,O are `2.1, 0.8` and `3.5` respectively comment on the nature of the compound `H-O-X`, that is :

The electronegativity of H, O and X are 2.1, 3.5 and 0.7 respectively. The correct nature of compound X-O-H is

The electronegativity values of C, H, O and N are 2.5, 1.0, 3.0 and 3.5 respectively: Which of the following is the most polar bond?

Aqueous solutions of two compounds M_(1)-OHandM_(2)-OH are prepared in two different beakers. If the E.N of M_(1) = 3.4, M_(2) =1.2, O = 3.5 and H = 2.1 then the nature of two solutions will be respectively

Nature of bond can be predicted on the basis of electronativity of bonded atoms, greater difference in electronegativity (X), more will be the polarity of bond, and polar bond are easily broken in polar solvent like water. For hydroxy acids X_(0) - X_(A) difference predict the nature of oxide formed by the element A. |X_(0) - X_(A)| gt |X_(0) - X_(H)| then A-O-H show basic nature (NaOH) |X_(0) - X_(A)| lt |X_(0) - X_(H)| then A-O-H show acidic nature (H-O-CI) With the help of EN values [EN_(A) = 1.8, EN_(B) = 2.6, EN_(C) = 1.6, EN_(D) = 2.8] answer the following questions for the compounds HAO, HBO, HCO, HDO . Percentage ionic character of compound AB is
