Among the following compounds, the most acidic is:                   [JEE-2011]

  • a)

    p - nitrophenol

  • b)

    p - hydroxybenzoic acid

  • c)

    o - hydroxybenzoic acid

  • d)

    p - toluic acid

Correct answer is option 'C'.

Ortho-isomer, a strong hydrogen bridge can be formed between the phenolic -OH and the the carboxylate anion. This will tend to stabilize the conjugated carboxylate base, and hence will increase acidity.

this is the order of acidic 

ortho hydroxy B.acid > meta hydroxy B.acid > benzoic acid > para hydroxy B. acids.

  • Force that resists motion of one body over another with which it is in contact.
  • Denoted by fk
  • As motion starts, fs vanishes and fk appears
  • Kinetic friction is Independent of the area of contact and velocity of the body
  • It varies with Normal reaction, N

fk ∝ N

fk = constant * N

fk = μk N; μk is the coefficient of kinetic friction

Mycorrhiza is a symbiotic association of fungi with the root systems of some plants. The fungal hyphae either form a dense network around the young roots or they penetrate the cells of the roots. The large surface area of the fungal hyphae is helpful in increasing the absorption of water and minerals from the soil. In return, they get sugar and nitrogenous compounds from the host plants. The mycorrhizal association is obligate in some plants. For example, Pinus seeds do not germinate and establish in the absence of mycorrhizal.
