Decide whether statement 1 is true, whether statement 2 is true, and whether the REASONING (the ‘BECAUSE’ relationship) between them is valid. Statement 1: “Pentanal has a higher Rf than 1-pentanol in a TLC analysis on a silica gel plate” BECAUSE Statement 2: “both aldehyde and alcohol molecules are attracted to silica by their permanent dipole moments, but only alcohol molecules can donate protons to form hydrogen bonds to silica”.   Question 10 options: A Statement 1 and statement 2 are both correct, and the reasoning is valid B Statement 1 and statement 2 are both correct, but the reasoning is NOT valid C Statement 1 is correct, but statement 2 is NOT correct         D Statement 1 is NOT correct, but statement 2 is correct E Statement 1 and statement 2 are both NOT correct
