III. List the following carbonyl compounds in order of decreasing pKa: 2,4-pentanedione, diethyl malonate, propanal, ethyl acetate (5%)

3.For the voltage divider with I = 90 μA, shown in Fig. 3, e MOSFET has VT = 1V, μnCox = 20 μA/V2, and neglect the effectof ro. Design the W/L ratio of each Q1, Q2, and Q3 MOSFETs suchthat the source voltage V1 of the transistor Q1 is +1 V and sourcevoltage V2 of the transistor Q2 is -1 V. (18%, Each sub-questiontakes 6 %)
