Context: The NBA high school draftees are players who have been drafted to the National Basketball Association (NBA) straight out of high school without playing basketball at the collegiate level. The process of jumping directly from high school to the professional level is also known as going prep-to-pro. Since 2006, the practice of drafting high school players has been prohibited by the new collective bargaining agreement, which requires that players who entered the draft be 19 years of age and at least one year removed from high school. Contrary to popular belief, the player does not have to play at least a year in college basketball, as the player can choose to instead play in another professional league (like the NBA G League or especially somewhere overseas) like Brandon Jennings or Emmanuel Mudiay in Italy and China respectively, simply take the year off, such as the case with Mitchell Robinson, or even hold themselves back a year in high school before declaring for the draft, like with Satnam Singh Bhamara or Thon Maker.
 Question: does the nba draft out of high school Context: Clark Kent's body is exhumed and placed in the amniotic fluid of the genesis chamber of the Kryptonian ship alongside the Mother Box, which in turn activates and successfully resurrects Superman. However, Superman's memories have not returned, and he attacks the group after Stone accidentally launches a projectile at him. On the verge of being killed by Superman, Batman enacts his contingency plan: Lois Lane. Superman calms down and leaves with Lane to his family home in Smallville, where he reflects and his memories slowly come back. In the turmoil, the last Mother Box is left unguarded and Steppenwolf retrieves it with ease. Without Superman to aid them, the five heroes travel to a village in Russia where Steppenwolf aims to unite the Mother Boxes once again to remake Earth. The team fights their way through the Parademons to reach Steppenwolf, although they are unable to distract him enough for Stone to separate the Mother boxes. Superman arrives and assists Allen in evacuating the city, as well as Stone in separating the Mother Boxes. The team defeats Steppenwolf, who, overcome with fear, is attacked by his own Parademons before they all teleport away.

The words alkene and olefin are often used interchangeably (see nomenclature section below). Acyclic alkenes, with only one double bond and no other functional groups, known as mono-enes, form a homologous series of hydrocarbons with the general formula CH. Alkenes have two hydrogen atoms fewer than the corresponding alkane (with the same number of carbon atoms). The simplest alkene, ethylene (CH), with the International Union of Pure and Applied Chemistry (IUPAC) name ethene, is the organic compound produced on the largest scale industrially. Aromatic compounds are often drawn as cyclic alkenes, but their structure and properties are different and they are not considered to be alkenes.
