... To reach the next equivalence point, you’d need another equivalence of NaOH (in other words, to reach the first equivalence point, you needed 0.00100 mol, and to reach the second equivalence point, you’d need 0.00200 mol – double the first.) You’re only halfway to the second equivalence point, here ...

... absorption at 3000 – 3500 cm , and two medium signals at 1580 and 1500 cm . The compound does not react with 2,4-dinitrophenylhydrazine (2,4-D). Upon treatment with I2/NaOH, A is oxidized and gives a positive iodoform reaction. Ozonolysis of A (1. O3; 2. Zn, H+) gives B (C9H10O) and C (C3H6O2). Both ...
