The structure of a typical methoxy group. In organic chemistry, a methoxy group is the functional group consisting of a methyl group bound to oxygen.This alkoxy group has the formula R−O−CH 3.

As time progressed, No. 578 and the rest of the N&W's 4-6-2s were reassigned to pull short-distance passenger trains, as well as commuter trains on branchlines, when the K class 4-8-2 "Mountain" types and J class 4-8-4 "Northerns" were built and assigned to pull the high-priority trains. Towards the end of the 1940s, No. 578's original tender ...
Another class of oxonium ions encountered in organic chemistry is the oxocarbenium ions, obtained by protonation or alkylation of a carbonyl group e.g. R−C= + −R′ which forms a resonance structure with the fully-fledged carbocation R− + −O−R′ and is therefore especially stable:
Norfolk and Western 433 is a preserved class M 4-8-0 "Mastodon" type steam locomotive built by the American Locomotive Company's Richmond Locomotive Works in January 1907 for the Norfolk and Western Railway. It was one of 125 M Class engines in operation on the N&W for around 50 years.
In March 1918, the Norfolk and Western Railway (N&W), which had been experimenting with Mallet locomotives to satisfy their growing mainline coal traffic over the Blue Ridge Mountains, introduced Y2 class 2-8-8-2 No. 1700, which was constructed at the Railway's shops in Roanoke, Virginia.
The Norfolk and Western M, M1 and M2 Classes were a series of 4-8-0 steam locomotives owned and operated by the Norfolk and Western Railway (N&W). The M Classes were primarily assigned to pull the N&W's mainline freight trains, but following the introduction of the railway's Y Class 2-8-8-2's, the M Classes were reassigned to short line freight service.
Anisole undergoes electrophilic aromatic substitution reaction at a faster speed than benzene, which in turn reacts more quickly than nitrobenzene.The methoxy group is an ortho/para directing group, which means that electrophilic substitution preferentially occurs at these three sites.
