Determine if each of the following is True or False:   True Acetals of sugars only open to carbonyls in acidic conditions so are non-reducing. True Hemiacetals and acetals are more reactive in acidic conditions than alcohols or ethers. True It is possible to selectively form or break bonds at the anomeric carbon vs. other carbons in a carbohydrate. True Reactions in basic conditions will tend to keep the stereochemistry of the anomer, while reactions in acidic conditions will tend to mix the stereochemistry of the anomer. True Alcohols in carbohydrates form ethers analogously to simple alcohols. False Reducing sugars are always ketoses.
