Re: ISAT Answers
As you want I am here giving you sample paper for ISAT Entrance Test of Indian Institute of Space Science and Technology (IIST) with answers. Sample paper : 26. The approximate standard enthalpies of formation----- Ans : DH (octane) is more negative than DH (methanol) Sol: Combustion of C8H8 involves more number of carbons and hydrogens compared to CH4O The reduction potentials of M2+ / M follow the trend------ Ans : V < Fe < Ni < Cu Sol: o M / M2 E + for V = - 1.18 V Fe = - 0.44 V Ni = - 0.25 V Cu = 0.34 V In the conversion of dinitrogen to hydrazine, ----- Ans : 4 and 4 Sol: N2 + 4H+ + 4e- ® N2H4 The compounds that form stable hydrates are----- Ans : II and IV Sol: II is Indane-1,2,3-trione. It forms a stable hydrate known as ninhydrin which is stabilized by intramolecular hydrogen bonding. IV is chloral which also forms stable chloral hydrate The stability order of the following carbocation is- ---- Ans : II > III > I > IV Sol: II is the most stable carbocation because positive charge is at allylic position with respect to two double bonds. IV is the least stable carbocation as it is Antiaromatic Here is the attachment . ISAT solved paper |
