trichloride, ICl, will react with a chloride ion to form IClr. Which species, if any acts as a Lewis acid this reaction? a.ICI4 b. ICl d. the solvent 20. Which of the following is a Lewis base? a. BCls b. Cu c. ch e.NH4 21. When 1 MNHs is added to a solution of copper'(II) nitrate, the following overall equilibrium is established to form a copper(II) tetraammine complex Which of the following changes to the copper(II) tetraammine reaction at equilibrium will result in an increase in the concentration of (Cu(H o)] ag)? Note: The formation constant, Ki, for [Cu(en) 0H,0)] (a?) is 1.6x 10) (a) addition of 1MHNO (b) addition of 1MNH (c) addition of IMNaCl (d) addition of 1Methylenediamine (en)Explanation / Answer
19. A lewis acid is a substance which accepts a pair of non-bonding electrons. Thus, lewis acid is an electron-pair acceptor.
In the question, ICl3 reacts with Cl- and forms ICl4-.
Thus, ICl3 accepts the electron pair here, from Cl- so ICl3 is the lewis acid .
OptionB.
