Question

1) If the intermolecular forces between molecules ofliquid (A) are ionic and the intermolecular forces betweenmolecules of liquid (B) are induced dipole-induced dipole forces(covalent) then___________.

A) (A) and (B) will be soluble anddelta S (change in entropy) is positive

B) (A) and (B) will be soluble and DSis negative

C) (A) and (B) will be insoluble and DSis positive

D) (A) and (B) will be insoluble and DSis negative


9) In the synthesis of cyclohexene the yield is maximized by____________.

   A) increasing the reactiontemperature          B)shifting the equilibrium by removal of H2O

   C) adding the gettertoluene                             D) both (B) and (C)

11) Which reagent or reagents would allow you to distinguishbutyne-2 from butene-2 ?

   A) KMNO4 in 95%ethanol       B) Br2 inCH2Cl2        C) both (A) and (B)       D) none ofthese

Explanation / Answer

We Know that :    If the intermolecular forces between molecules ofliquid (A) are ionic and the intermolecular forces betweenmolecules of liquid (B) are induced dipole-induced dipole forces(covalent) then :      A) (A) and (B) will besoluble and delta S (change in entropy) ispositive.    In the synthesis of cyclohexene the yield ismaximized from cyclohexanol      A) increasing the reactiontemperature        Which reagent or reagents wouldallow you to distinguish butyne-2 frombutene-2          none of these          Bothalkaline KMnO4 and Br2 +CH2Cl2 helps to detect the unsaturationto distinguish alkene and alkyne we should          observe the number of moles of H2 to obtain thesaturated product.                   none of these          Bothalkaline KMnO4 and Br2 +CH2Cl2 helps to detect the unsaturationto distinguish alkene and alkyne we should          observe the number of moles of H2 to obtain thesaturated product.
