Dicliptera resupinata, the Arizona foldwing, is a perennial plant in the Acanthaceae family. It is native to higher areas of southeastern Arizona into Mexico. [ 1 ] It is a host to the Texan crescentspot ( Anthanassa texana ).
Acyclic aliphatic/non-aromatic compound Cyclic aliphatic/non-aromatic compound (cyclobutane)In organic chemistry, hydrocarbons (compounds composed solely of carbon and hydrogen) are divided into two classes: aromatic compounds and aliphatic compounds (/ ˌ æ l ɪ ˈ f æ t ɪ k /; G. aleiphar, fat, oil).
Heteroarenes are aromatic compounds, where at least one methine or vinylene (-C= or -CH=CH-) group is replaced by a heteroatom: oxygen, nitrogen, or sulfur. [3] Examples of non-benzene compounds with aromatic properties are furan, a heterocyclic compound with a five-membered ring that includes a single oxygen atom, and pyridine, a heterocyclic compound with a six-membered ring containing one ...
A “pretty flower” popping up in a southern Arizona national park is a big problem — and officials are asking the public for help.. Stinknet has bright, yellow ball-like flowers with ...
Nevertheless, many non-benzene aromatic compounds exist. In living organisms, for example, the most common aromatic rings are the double-ringed bases in RNA and DNA. A functional group or other substituent that is aromatic is called an aryl group. The earliest use of the term “aromatic” was in an article by August Wilhelm Hofmann in 1855.
Big sagebrush is a coarse, many-branched, pale-grey shrub with yellow flowers and silvery-grey foliage, which is generally 0.5–3 metres (1 + 1 ⁄ 2 –10 feet) tall. [3] A deep taproot 1–4 m (3 + 1 ⁄ 2 –13 ft) in length, coupled with laterally spreading roots near the surface, allows sagebrush to gather water from both surface precipitation and the water table several meters beneath.
Ipomoea alba is a perennial, herbaceous liana growing to a height of 5–30 m (20–100 ft) tall with twining stems. The leaves are entire or three-lobed, 5–15 cm (2–6 in) long, with a stem 5–20 cm (2–8 in) long.
Cyclopropane is the smallest alicyclic compound. In organic chemistry, an alicyclic compound contains one or more all-carbon rings which may be either saturated or unsaturated, but do not have aromatic character. [1] Alicyclic compounds may have one or more aliphatic side chains attached.
