ROUND: â This function is used for rounding a number to a specified number of digits. For Example:Cell A1 is contains the number 456.25. To round the number, follow below given steps:-. Write the formula in cell B1.
The boiling point of the alcohol ethanol is 78.29 Â°C, compared to 69 Â°C for the hydrocarbon hexane (a common constituent of gasoline), and 34.6 Â°C for diethyl ether. Alcohols, like water, can show either acidic or basic properties at the-OH group.With a pKa of around 16-19, they are, in general, slightly weaker acids than water, but they are still able to react with strong bases such as sodium hydride or reactive metals such as sodium.he boiling point of the alcohol ethanol is 78.29 Â°C, compared to 69 Â°C for the hydrocarbon hexane (a common constituent of gasoline), and 34.6 Â°C for diethyl ether. Alcohols, like water, can show either acidic or basic properties at the-OH group.
Glucose is more acidic than simple alcohols with a pK a of about 12 (K a = 10 -12). Compare this to methanol with a pK a of 15.5 (K a = 10 -15.5). The electronegative oxygen atoms in the molecule pull electron density away from the carbon atom bearing the negatively charged oxygen in the conjugate base, stabilizing it.he hydrogen is a little less electronegative than the carbon so a C-H bond is slightly polarized with more electron density on carbon. Excess electron density on a carbon adjacent to a negatively charged oxygen atom (in the alkoxide) destabilizes the conjugate base and makes the acid a little weaker.
