Competition experiment between SN2 and E2. With ethyl bromide, the reaction product is predominantly the substitution product. As steric hindrance around the electrophilic center increases, as with isobutyl bromide, substitution is disfavored and elimination is the predominant reaction. Other factors favoring elimination are the strength of the ...
Reactive nitrogen ("Nr"), also known as fixed nitrogen [1], refers to all forms of nitrogen present in the environment except for molecular nitrogen (N 2 ). [ 2 ] While nitrogen is an essential element for life on Earth, molecular nitrogen is comparatively unreactive, and must be converted to other chemical forms via nitrogen fixation before it ...
The semi-solid mixture can also be called slush nitrogen [63] or SN2. [64] Solid nitrogen is used as a matrix on which to store and study reactive chemical species, such as free radicals or isolated atoms. [65] One use is to study dinitrogen complexes of metals in isolation from other molecules. [66]
The debate's virality became a meme in and of itself, as one poster suggested that there was greater conversation about the faceoff than some birthdays. Harris' reactions add to meme library

The term meme is a shortening (modeled on gene) of mimeme, which comes from Ancient Greek mīmēma (μίμημα; pronounced [míːmɛːma]), meaning 'imitated thing', itself from mimeisthai (μιμεῖσθαι, 'to imitate'), from mimos (μῖμος, 'mime').
A period 5 element is one of the chemical elements in the fifth row (or period) of the periodic table of the chemical elements.The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behaviour of the elements as their atomic number increases: a new row is begun when chemical behaviour begins to repeat, meaning that elements with similar behaviour fall ...
