The first part of this reaction is an aldol reaction, the second part a dehydration--an elimination reaction (Involves removal of a water molecule or an alcohol molecule). Dehydration may be accompanied by decarboxylation when an activated carboxyl group is present. The aldol addition product can be dehydrated via two mechanisms; a strong base like potassium t-butoxide, potassium hydroxide or sodium hydride in an enolate mechanism, or in an acid-catalyzed enol mechanism. Depending on the nature of the desired product, the aldol condensation may be carried out under two broad types of conditions: kinetic control or thermodynamic control.

OPTIONS:
- no
- yes

can aldol condensation take place in acidic medium?

A: yes

Pepsi Zero Sugar (known as Diet Pepsi Max until early 2009 and Pepsi Max until August 2016), is a zero-calorie, sugar-free, carbohydrate-free, ginseng-infused cola sweetened with aspartame, marketed by PepsiCo. It has nearly twice the caffeine of Pepsi's other cola beverages. Pepsi used airtime during Super Bowl XLII to advertise the beverage; the commercial featured the song ''What Is Love'' by Haddaway, and showed people sleeping in inappropriate places and at inappropriate times, while bobbing their heads to the rhythm of the song. Pepsi Max's current slogan in the US is ''Maximum taste. Zero calories.'' In July 2010, Pepsi Max had a commercial remake from the 1995 diner commercial. The commercial includes the song ''Why Can't We Be Friends?'' by War. In 2011, Snoop Dogg was featured in an ad campaign around the time of Super Bowl XLV.

- no
- yes

is pepsi max the same as pepsi zero?

A: yes

Skunks are probably best known for their ability to spray foul-smelling fluid as a defense against predators. Most wild skunks spray only when injured or attacked, as a defense mechanism. The mercaptan-emitting scent glands are usually removed in pet skunks at about four weeks of age. Since 2006, this removal practice has been illegal in the UK.

OPTIONS:
- no
- yes

can you take a skunk's stinker out?

A: yes

Equus is a genus of mammals in the family Equidae, which includes horses, donkeys, and zebras. Within Equidae, Equus is the only recognized extant genus, comprising seven living species. The term equine refers to any member of this genus, including horses. Like Equidae more broadly, Equus has numerous extinct species known only from fossils. The genus most likely originated in North America and spread quickly to the Old World. Equines are odd-toed ungulates with slender legs, long heads, relatively long necks, manes (erect in most subspecies), and long tails. All species are herbivorous, and mostly grazers, with simpler digestive systems than ruminants, but able to subsist on lower-quality vegetation.

OPTIONS:
- no
- yes

are horses donkeys and zebras the same species?

A:
no
